Hello. Does anyone try to prepare COS7 cells for analysis of cell-surface
antigen with FACS? When I treated cells with PBS/5mM EDTA(pH 7.2) to
prepare single-cell suspension, the efficiency is nearly 20-40% and most of
cells still remains undispersed. I also tried the increase of EDTA
concentration (up to 25mM) and the addition of BSA(1%), but no improvement
was observed. What buffer is suitable for this study? Any comments and
suggestions will welcome.
