post sorting fibroblast viability

try using PBS or any other uncolored medium as sheeth fluid, we found that
the BDIS sheath (as also Coulters and some others) modify/inhibit the
growth of some sensitive cellines after sorting (I suppose its some
growthinhibitors or stabilizers in the commercial fluids).

Might not be the reason, but could be worth a trial.

Cheers, Matthias
