Detection of FITC oligos

I have a query regarding detection of fluoresceinated oligos
intracellularly by FACS. Is it possible to distinguish between
externally bound liposome/oligo complexes and internalised intracellular
complexes by FACS following transfection of mammalian cells? I know
that I could use a microscope (heaven forbid!) but the number of samples
and the need for quantitation w.r.t. transfection efficiency preclude
that option (plus I'm very attached to my FACSort so would always choose
that over a microscope if I had a choice). Maybe there is a way to
strip off non-internalised oligos so you can be sure you're measuring
only internal fluorescence? Any tips from users who have tried this
would be very much appreciated.
Thanks in advance,
Michelle Miller
