Both the nascent

SVMPs and the processed DC domains have been isolated from viperoid venoms (Fox and Serrano, 2005 and Fox and Serrano, 2008). In the present work, we describe the isolation procedure and partial PR-171 supplier characterization of a fibrinogenolytic metalloproteinase from B. moojeni venom, which belongs to the PIIIb subclass of SVMPs. Desiccated B. moojeni venom was purchased from Bioagents Serpentarium (Batatais-SP, Brazil). Acrylamide, ammonium bicarbonate, ammonium persulfate, benzamidine, bromophenol blue, ethylenediaminetetracetic acid (EDTA), bovine fibrinogen, β-mercaptoethanol, N,N′-methylene-bis-acrylamide, leupeptin, phenanthroline, phenylmethylsulphonyl fluoride (PMSF), sodium dodecyl sulfate (SDS) and N,N,N′,N′-tetramethylethylenediame (TEMED) were purchased from Sigma Chemical Co. (St. Louis, MO, USA). Glycine, Tris, molecular weight markers for electrophoresis and all chromatographic media were purchased from GE Healthcare (Sweden). All other reagents used were of analytical grade. Male Swiss mice (20 g ± 5 g) were obtained from Centro de Bioterismo e Experimentação Animal (CEBEA) at the Federal University of Uberlândia

(Uberlândia-MG, Brazil). The animals were housed in a temperature-controlled room (23 °C) on an automatic 12 h light/dark cycle (light phase 6 a.m. to 6 p.m.). Food and water were freely available until the beginning of the experiments. The experimental protocol was approved by the Ethics Committee on Animal Experimentation of the Federal University of Uberlândia (CEUA/UFU, Protocol number 028/09). Protein isolation was carried out in two stages. Crude B. moojeni venom (400 mg) was dispersed in 2.0 mL of 0.05 M ammonium bicarbonate buffer (pH 7.8), clarified by centrifugation at 10,000 × g for 10 min and applied on a DEAE-Sephacel column (1.5 × 15 cm). Chromatography was carried out at a flow rate of 40 mL/h, with a convex concentration gradient of the same buffer (0.05–0.6 M). The seventh fraction,

named D7, was pooled, lyophilized, dissolved in 2.0 mL of 0.05 M ammonium bicarbonate (pH 7.8) and submitted to second stage separation 17-DMAG (Alvespimycin) HCl using a HiPrep Sephacryl S-300 column (2.6 × 60 cm). Samples were eluted from this column with the same buffer at a flow rate of 1 mL/min. All peaks were monitored by measuring absorbance at 280 nm. The isolated enzyme was named moojenin. To evaluate the degree of purity, the isolated moojenin was passed through a reverse-phase C2/C18 column (4.6 × 100 mm) using an FPLC Äkta Purifier UPC-10 system (GE Healthcare, Uppsala, Sweden). The column was equilibrated with solvent A (0.1% trifluoroacetic acid), and eluted with a linear concentration gradient from 0 to 100% of solvent B (70% acetonitrile, 0.1% trifluoroacetic acid), at a flow rate of 0.5 mL/min for 93 min. Absorbance was monitored at 280 nm.

suggesting that non-surgical management is an acceptable option. In addition, the recognition of extensive LM positivity as a risk factor for residual/locally recurrent cancer would AZD2281 be helpful in selecting cases that may necessitate strict management such as immediate additional endoscopic treatment.

“Endoscopic submucosal dissection (ESD) is accepted as a treatment for gastric neoplasms. Several trials have shown the efficacy of gastric acid secretion inhibitors for post-ESD ulcers. However, to date there has been no consensus regarding the optimal drug regimens. Irsogladine has previously been shown to accelerate the healing of

gastric ulcers after Helicobacter pylori (H. pylori) eradication therapy. Hence, we conducted a randomized controlled trial to compare proton pump inhibitor (PPI) and combination PPI plus irsogladine treatments. To assess the efficacy check details of PPI and irsogladine combination therapy compared with PPI monotherapy for ESD-induced gastric ulcer healing. Ninety Six ESD-induced gastric ulcer patients

were enrolled in this study. In Group A(n=51), subjects received rabeprazole 10 mg/day and irsogladine 4 mg/day for 8 weeks and in Group B(n=45), subjects received rabeprazole 10 mg/day for 8 weeks. At 1, 4 and 8 weeks after ESD, we performed endoscopic examination to assess each gastric ulcer healing. There was no significant difference between group A and group B in the patient’s background. The ulcer healing rates at 4 weeks after ESD in group A were significantly higher than those in group B in the full analysis set (19.6% vs 5.13%; P < 0.05, chi-square test). The concomitant use of PPI and irsogladine was more effective than the PPI alone for treating Dehydratase ulcers within 4 weeks after ESD. Therefore, the combination therapy of PPI and irsogladine was favorable regimen in patients with artificial ulcer after ESD. “
“Subepithelial tumors (SETs) can be challenging to diagnose and treat by endoscopy. Biopsies may not reach the tumor and endoscopic ultrasound (EUS)-guided tissue acquisition can be difficult due to small lesion size and mobility. Resection has been reported, but carries inherent risks of bleeding and perforation. Loop ligation can achieve ischemic tumor ablation, but may not capture broad-based lesions, and does not address tissue acquisition for diagnosis.

Figure 4A shows a different set of biopsy samples visualized under white light following treatment with the AF350-WGA probe. The fluorescent lamp used for white Sirolimus price light imaging may have caused uneven tissue illumination, resulting

in the cancerous tissue looking brighter in Figure 4A. However, tissue appearance differences between normal and diseased tissue is well established due to increased cell density, protein amounts, etc. Typically, these lesions are often times whiter in appearance which would have caused them to appear brighter under white light imaging. Nevertheless, increased probe fluorescence is noted on the tumor specimen and not the normal specimen ( Figure 4B), proving the specificity of the probe for the overexpressed glycan residues on the tumor surface. Lastly, Figure 4C shows a digital camera image of tissue biopsies incubated in AF350-WGA to capture fluorescent images that would more accurately demonstrate the conditions observed within a clinical setting; this image shows the enhanced fluorescence is easily visible

with the naked eye. Similar results were seen for all tissue samples tested with AF350-WGA and are summarized in Figure 5 and in Table 2. Figure 5 shows the patient/tissue samples’ SNR for AF350-WGA testing. The AF350-WGA fluorescence of the cancerous tissue was statistically significantly higher than that of normal tissue with an average SNR of 5.88 ± 3.46 (P AG-014699 mw = .00046, Table 2). The differences observed amongst the SNRs can be attributed to the fact that sialic acid overexpression is dependent on patient variability, disease progression, cancer aggressiveness, etc. However, it is important to note that all patients displayed SNRs greater than 3. The UV autofluorescence of the cancerous tissue displayed an average SNR of 1.35 ± 0.41 and was not statistically significantly Phosphoglycerate kinase different than normal tissue (P = .098, Table 2). The SNR of AF350-WGA was statistically significantly larger than the SNR for UV autofluorescence (P = .0049, Table 2) with it being at

least double the ratio in all seven patients. To further validate the specificity of the WGA binding conjugate, inhibitory experiments were carried out with N-acetyl glucosamine which serves to block the available binding sites of WGA prior to sample application. Pre-incubation of AF350-WGA with the sugar resulted in a threefold decrease in fluorescence intensities of the cancerous tissue (Figure 6), indicating that the soluble sugar competitively inhibited the WGA from binding to the overexpressed glycan residues on the cancerous cell surface. Interestingly, the inhibited AF350-WGA still resulted in higher fluorescence intensity values from the cancerous tissue when compared to the normal tissue (Figure 6B and C).

Under acidic conditions, calcium and magnesium supply is reduced

Under acidic conditions, calcium and magnesium supply is reduced and plant growth suffers. In addition to these effects, other beneficial nutrients, such as nitrogen, phosphorus, and sulfur, are also in deficient concentration. The low yields of groundnut are due to poor pod filling in acid soils, owing to poor calcium-supplying power of soils. For meeting calcium demands and creating favorable conditions for better uptake of other essential nutrients, particularly phosphorus, liming is an important management practice in acid soils. The improvement of these acid soils should also aim at eliminating

the toxic effects of Al and Mn. The check details harmful effects of soil acidity can be eliminated by raising pH with suitable quantities of lime. Liming helps in raising the base saturation of the soil PLX-4720 in vivo and inactivating iron, aluminum, and manganese in the soil solution. Liming also helps to minimize phosphate fixation by iron and aluminum. Kamprath [8] reported the need for raising soil pH beyond the point of neutralizing

exchangeable aluminum, particularly for legumes. Recently, high-yielding cultivars of ricebean in northeastern states of India including Nagaland have been developed with extra short duration, bold seed, and dwarf plant types suitable for cultivation. These cultivars must be evaluated under different levels of lime in acid soils of the Nagaland foothills in the post-rainy season. The present investigation

was undertaken with the following objectives: (i) to evaluate the effect of lime on growth, yield attributes, yield, economics, and quality parameters, (ii) to evaluate the effect of lime on soil health, and (iii) to prescribe the best ricebean cultivars under foothill conditions during the post-rainy season. The field experiment was conducted during the post-rainy seasons of 2010–2011 and 2011–2012 at the Agricultural not Research Farm of ICAR, RC for NEH Region, Nagaland Centre, Jharnapani, Nagaland, India. The experimental site was located at 25.45° N latitude 93.53° E longitude with a mean altitude of 295 m ASL. The climate of the experimental site was subtropical with high humidity and medium to high rainfall. The soil was sandy loam and acidic in reaction (pH 4.9). The soil contained 0.95% oxidizable organic carbon, 235 kg ha− 1 mineralizable nitrogen, 136 kg ha− 1 available potassium, and 10.3 kg ha− 1 available phosphorus. During the experimental period the maximum and minimum temperatures varied from 23.0 °C to 31.1 °C and 9.7 °C to 24.0 °C, respectively, during 2010–2011 and 24.3 °C to 31.2 °C and 9.5 °C to 24.2 °C during 2011–2012. The maximum and minimum relative humidities ranged from 75% to 84% and 38% to 67%, respectively, during 2010–2011 and 78% to 85% and 78% to 63% during 2011–2012. Total precipitations of 225.2 mm and 315.

It has also been suggested that because the vestibular system pla

It has also been suggested that because the vestibular system plays a role in controlling autonomic functions (e.g. heart rate, blood pressure) (Yates and Miller, 1998), alterations to these autonomic functions may also trigger a range of changes in cognition, emotion and personality. There are

several reports that suggest patients with vestibular disturbance experience symptoms of depression, anxiety and agoraphobia at higher rates than the general population (Eagger et al., 1992, Gazzola et al., 2009 and Guidetti et al., 2008). In a study of 93 patients with objective evidence of peripheral vestibular disorder two thirds of the patients reported symptoms of depression and/or anxiety since the onset of the vestibular symptoms. Fifty-four of these patients were

seen 3 to 5 years after their original referral and more than half the group (37 out of 54) were rated above the cut off point for GSK-3 inhibitor significant psychiatric disturbance when interviewed. Panic disorder with or without agoraphobia and major depression were the commonest psychiatric diagnoses. There is some evidence to suggest that these symptoms are more than a reaction to the symptoms of vestibular dysfunction (e.g. vertigo or dizziness). For example, Guidetti et al., (2008) reported significantly higher AZD4547 mw levels of anxiety and depression in 50 patients with well compensated (no vertigo symptoms) unilateral labyrinthine hypofunction as a consequence of previous vestibular neuritis

as compared to 50 age- and sex-matched healthy controls. Somewhat contrasting these findings is a recent prospective study that looked at predictors of anxiety (STAI) and depression (BDI) in 407 patients who presented with dizziness and vestibular disease (194 patients were diagnosed with BPPV, 75 with vestibular neuritis, 63 with Ménière′s disease, 58 with migrainous vertigo, and Clomifene 17 with presbystasis). Results suggested that rather than the type of vestibular disease, the best predictor of depression and anxiety was the patient′s level of distress associated with symptoms of dizziness or vertigo (dizziness handicap inventory scores) (Hong et al., 2013). A series of prospective, interdisciplinary studies were conducted to explore the relationship between comorbid psychiatric disorders and symptoms in patients with various organic vertigo syndromes (Best et al., 2006 and Eckhardt-Henn et al., 2008). Patients with organic vertigo syndromes (benign paroxysmal positioning vertigo—BPPV; vestibular neuritis; Menière′s disease; vestibular migraine), and healthy volunteers were assessed on the Symptom-Check List 90 (a standardised, self-reporting instrument that measures psychological strain) and The structural clinical interview for DSM-IV Axis I (SCID-I). Results of the initial study (Best et al.

It was observed that extreme water levels rise towards the inside of the bay – this is called the bay effect. Palbociclib The Bay of Mecklenburg is that part of the Baltic Sea where the greatest falls in sea level due to storm surges have been recorded (levels lower than − 140 cm), which is associated with the relatively small depths and

the above-mentioned bay effect. The Swedish coasts of the central Baltic (the Northern and Southern Baltic Proper, Western Gotland Basin) are the least exposed to extreme sea levels. This is determined mainly by the easterly exposure of the coast, i.e. the direction opposite to that in which low pressure systems propagate. The results are consistent

with the work of Averkiev and Venetoclax nmr Klevanny, 2007 and Averkiev and Klevanny, 2010, Suursaar et al., 2003 and Suursaar et al., 2007, Stigge (1994), Jensen & Müller-Navarra (2008), Johansson (2004), Sztobryn et al., 2005 and Sztobryn et al., 2009, according to which the south-western and eastern coasts of the Baltic Sea (Bay of Mecklenburg, Gulf of Riga, Gulf of Finland, the northern part of the Bothnian Bay) are exposed to especially dangerous storm surges caused by the deep troughs of low pressure passing through these regions. Detailed data on the occurrence of maximum and minimum sea levels from 1960 to 2010 3-mercaptopyruvate sulfurtransferase for different areas of the Baltic Sea are presented in Table 1. The adoption of

the European Vertical Reference System (EVRS 2000) by the Baltic states has enabled all observational data to be converted into one reference level NAP and to show the topography of the surface waters in the whole Baltic Sea area. Owing to the complex nature of the phenomenon, the analysis of extreme changes in water levels during storm surges is complicated. It is hindered by the fact that changes in sea level are largely affected by local conditions – the configuration of the coastline, as well as the morphology and bathymetry of the coastal zone. Therefore, when analysing extreme water levels, it is important to determine the long-term probability forecast based on the longest observation series of maximum and minimum annual sea levels. Probability analysis determines the so-called theoretical sea levels that may occur once in a number of years, e.g. once in 50 or 100 years.

To detect the differences in macrophage differentiation,

ANOVA for paired samples was used, followed by Fisher’s least significant different test. Correlations were BGB324 purchase evaluated by Spearman’s test. The criterion of significance was set to p < 0.05. To investigate the effect of soluble Aβ-peptides on the phagocytosis of PSPs by freshly isolated human monocytes, the cells were pre-incubated with 1 μg/ml of the respective Aβ-peptide in cell culture medium. Then, 20 h after adding the fluorescent PSPs, phagocytosis was quantified by flow cytometry. The MFI of the phagocytes was used as a measure of the number of internalized fluorescent particles. The pre-incubation of monocytes with Aβ(1–42) as well as the N-terminally truncated Aβ(2–40) and Aβ(2–42), but not Aβ(1–40), induced phagocytosis at levels significantly above the control levels (p < 0.05) ( Fig. 1A). Monocytes treated with Aβ(2–40) internalized 17% more PSPs than those treated with full-length Aβ(1–40) (p < 0.05). The treatment of cells

with BSA did not influence the phagocytosis of PSPs. To assess whether the Aβ-peptides secreted by monocytes enhanced phagocytosis by binding to pathogens, the effect of Aβ-coated PSPs on their phagocytosis by human monocytes was examined. The phagocytosis of fluorescent particles was quantified by flow cytometry as described above (Fig. 1B). Precoating the fluorescent PSPs with all of the tested Aβ-peptides increased their phagocytosis by monocytes compared to the phagocytosis of uncoated PSP (p < 0.001). Coating the PSPs with Aβ(1–42) enhanced the amount of phagocytosed PSPs by 40% (p < 0.0001). Aβ(1–42) induced phagocytosis more effectively than Aβ(1–40) (p < 0.0001). The treatment

of monocytes with Aβ(2–42)− and Aβ(3p–42)-coated PSPs resulted in an even higher increase of the MFI values by 53% (p < 0.0001) and 56% (p < 0.0001), respectively. This result indicates that an additional Inositol monophosphatase 1 N-truncation of Aβ(1–42) further increased the phagocytosis of PSPs. In contrast to the treatment of monocytes with soluble Aβ-peptides, pre-incubation with n-truncated Aβ(2–40) did not enhance phagocytosis more effectively than Aβ(1–40). Because undifferentiated monocytes are poor phagocytes, cytochalasin D only weakly reduced phagocytosis. Phagocytosis of pHrodo Green-labeled E. coli, which is only fluorescent at an acidic pH, revealed that cytochalasin D completely inhibited phagocytosis in our setting ( Fig. 4F). Therefore, increased signal intensity after pretreatment with cytochalasin D and coincubation with permanently fluorescent prey indicated its binding to the phagocyte surface without internalization. To investigate whether the differential effects of the Aβ-peptides were due to different binding affinities for the PSPs, the amount of Aβ-peptide bound to the PSPs was quantified by immunostaining with the C- and N-terminal non-specific Aβ antibodies 6E10 and 4G8.

neural cells constituting brain tissue remains matter of debate. This review aims to summarize ET effects on the nervous system (mainly the central nervous system) and focuses on the causal linkage between symptoms or manifestations expressed by intoxicated animals as well as structures affected, and the potential direct effect of ET on neural cells. C. perfringens (also termed Clostridium welchii) is a Gram-positive, anaerobic and spore-forming bacillus. C. perfringens is a ubiquitous environmental bacterium that can be found as normal microflora component of soil, dust and sediments. As many click here other Clostridia, it grows in cadavers and litter. Spores are ingested and can reach intestines of various vertebrates ( McClane and Chakrabarti, 2004). Overall, C. perfringens is considered as a normal inhabitant of the gastro intestinal tract. Typically, perturbation of microbial balance in the gut (for instance by a rapid change in diet) induces overgrowth

of C. perfringens leading to production of high level of toxins. Proliferation of types B and D in gut causes enterotoxaemia in sheep and goat and more rarely in cattle ( Uzal et al., 2002; McClane and Chakrabarti, 2004). The bacterium has also been found in pig ( Bergeland, 1972; Bergeland et al., 1966; Cho et al., 1991) and smaller renting animals, such as rabbit and chicken ( Heikinheimo and Korkeala, 2005; Sting, 2009). ET-producing GBA3 strains of C. perfringens have Caspase inhibitor been isolated from human intestine ( Gleeson-White and Bullen, 1955; Kohn and Warrack, 1955) and upon the occasion of a case of gas-gangrene ( Morinaga et al., 1965). However, it remains

unclear whether the strains isolated had a role in the disease observed in man. 17 different toxins including alpha, beta, iota and epsilon toxins are produced by various strains of C. perfringens. According to produced-toxins, C. perfringens have been divided into five main groups, from A through E ( Finegold, 1977; Fisher et al., 2006; Niilo, 1980). Only two groups of C. perfringens (types B and D) produce ET. C. perfringens type B produces ET together with alpha-and beta-toxins whereas type D produces ET, alpha-toxin and perfringolysin-O (reviewed by Alouf and Popoff, 2006; McClane et al., 2006; Uzal and Songer, 2008). ET is a single-chain protein synthesized as a protoxin of 32–33 kDa (McDonel, 1980). Removal of the 11 N-terminal (or the 13 N-terminal) and of the 29 C-terminal residues amino-acids by proteases (notably the α-chymotrypsin, trypsin and λ-protease) converts the inactive protoxin (proET) into a fully active form (i.e. the toxin, ET 28.6 kDa), with a lethal dose (LD) of about 70 ng kg−1 in mice (i.e. 400,000 mouse-LD per mg protein) (Minami et al., 1997; reviewed by Popoff, 2011a). Proteases involved in conversion of proET into ET are synthesized by C. perfringens ( Minami et al.

The standard deviation does not show any clear dependence on time

The standard deviation does not show any clear dependence on time of year; nevertheless, SST assimilation selleck chemicals llc decreased its value in most

months. Application of the Cressman assimilation algorithm into the 3D CEMBS_A model improved its accuracy and conformance of its results with in situ and satellite measured SST. Analysis of the results gives a better view of the spatial and temporal error distribution in the investigated period of time. Overall, the statistics show an increase in model correlation with the satellite data from ca 0.95 for the 3D CMEBS model to ca 0.98 for 3D CMEBS_A. Also, the mean arithmetic error and standard deviation are smaller for the model with SST assimilation, which confirms the assimilation algorithm’s correctness. Similar results are obtained when the models are compared with in situ data. The correlation coefficient in this case increased from 0.957 to 0.973 and the systematic error decreased strongly in value.

In addition, the standard deviation decreased in value slightly. After removal of the main seasonal signal, the statistics of the model results presented in Table 3 reveal an even bigger difference in correlation between the two models and the in situ data. The simulations of SST are also better with respect to monthly means, as shown in Table 4 and Figure 12 and Figure 13. Assimilation of satellite data into the 3D CEMBS_A model is therefore reasonable, as is its further development. The ongoing development of the SST assimilation system as well as other parameters such as chlorophyll a is included ZD1839 chemical structure in our research plans.

“The thematic issue you are holding in your hands is a selection of papers presented at the 7th Study Conference on BALTEX which took place on the Swedish island of Öland from 10–14 June Thalidomide 2013. It was a very special event: it was the final conference for the BALTEX programme, and it was here that the successor programme Baltic Earth was launched in the presence of H. M. King Carl XVI Gustaf, King of Sweden. With this conference on Öland, we have returned to Sweden where the first BALTEX Study Conference had taken place in 1995 on Gotland. The conference was attended by 120 participants from 14 countries, mostly from countries in the Baltic Sea drainage basin: Sweden, Finland, Russia, Belarus, Estonia, Latvia, Lithuania, Poland, Germany and Denmark, but also from the Netherlands, France, Italy, UK and the US.

VeraCode™ beads are 240 × 28 μm, holographically encoded, glass m

VeraCode™ beads are 240 × 28 μm, holographically encoded, glass micro-cylinders with a carboxylated surface chemistry. First, 10,000 to 40,000 VeraCode™ beads were washed 3 × 800 μL with MES Buffer (0.1 M MES, pH 4.7, 0.9% NaCl) by sequential

mixing, pelleting the beads by brief and gentle spinning (or allowing beads to settle by gravity) and removing the supernatant (wash buffer) by manual pipetting, being careful not to lose the bead pellet. All washes were performed in this manner unless otherwise indicated. After discarding the final wash, 200 μL of Sulfo-NHS Buffer (1 mg/mL in MES Buffer; prepared immediately prior to use) was added to each washed bead pellet. Beads were mixed immediately and buy Thiazovivin briefly. 200 μL of EDC Buffer (1 mg/mL in MES Buffer; prepared immediately prior to use) PD0325901 was immediately added to each sample (containing both beads and Sulfo-NHS Buffer) and immediately mixed to combine. Following incubation for 1 h with mixing (all extended mixing steps for VeraCode™ beads were done at 1200 rpm on a VorTemp 56 shaker, Labnet International Inc., Edison, NJ), the beads were then washed 3 × 800 μL briefly with MES Buffer and then 1 × 800 μL quickly with 1 × PBS (for proteins or antibodies prepared in MES Buffer, this PBS wash was omitted). The protein coupling reaction immediately followed, in which 10–40 μg of the

previously prepared recombinant protein or 100 μg of antibody was added to the beads, mixed, and incubated for 1 h with mixing (a comprehensive titration analysis was not performed due to the wide range of protein classes and wide range of concentrations at which they were supplied by the manufacturers, however, the amounts added are believed to be sufficient to saturate the bead surface, as using a calculation of 2.5 mg/m2 binding capacity of a solid non-porous surface as reported for avidin and 15 mg/m2 for antibodies (Plant et al., 1991), we estimate that 40,000 beads can bind a maximum of roughly 2–10 μg). Beads were then spun

down, and the protein solution was removed. The beads were washed 2 × 800 μL briefly with BSA Block (1% BSA [w/v] in TBS-T; TBS = 50 mM Tris, pH 7.5, 200 mM NaCl; TBS-T contains 0.05% [v/v] Tween-20) before discarding the wash and incubation with an additional 400 μL of BSA Block for 30 min. N-acetylglucosamine-1-phosphate transferase Beads were then washed briefly 1 × with 800 μL of PBS-1 M NaCl, 1 × 30 min with 400 μL of PBS-1 M NaCl (with shaking) and then 2 times briefly with 800 μL TBS-T. Beads were stored in TBS-T at 4 °C. For optimal performance, we used an indirect method of coating VeraCode™ beads with biotin followed by streptavidin. Streptavidin beads were then used to in situ capture/purify cell-free produced proteins carrying the SBP-Tag (Keefe et al., 2001), directly from the crude expression reaction. First, a vial of 20,000 carboxyl-terminated VeraCode™ beads was washed 5 × 400 μL with MES Buffer (0.1 M MES, pH 4.7, 0.9% NaCl).
