I guess the answer depends on whether the events w/ low FS ansd SS are
apoptotic cells or debris or some other cell type [depending on the system].
For th e most part, the info you want is % apoptotic cells of a particular
population. So you need some method to determine whole cells [apoptotic or
live] from other events. If you can't achieve this with LS then maybe
adding a McAb or staining for DNA wil l be a required gating step.

Good luck,
Tom
