Hi
Maybe you could use colcemid to block your cells in mitosis then do your
PI and FITC. After 12 hours or so depending on how fast your cells grow the
majority of cells in the G2/M peak will be mitotic. With adherent cell
lines, blocking with colcemid then using mitotic shake-off yields a
suspension of almost exclusivly mitotic cells.
Have fun.
