After this incubation, the cell suspension was made up to 1 mL with sterile water. Analysis was performed using an EPICS XL-MCL flow cytometer (Beckman-Coulter, USA) equipped with an argon-ion laser emitting a 488 nm beam at 15 mW. An acquisition protocol was defined after measuring background fluorescence from non-treated BY4741 S. cerevisiae strain, and Δssd1 cells treated with 30 μM FITC-PAF26. Data (20,000 cells/sample) were
analyzed with the Expo32 software included in the system acquisition. Acknowledgements S. cerevisiae strain RAY3A and derivatives were kindly provided by Dr. CYT387 purchase José I.
