[Histonet] Need technique information

Hi all,

I have some slides of cultured cells which are immunostained, fixed in
4% PFA and sorted through a FACS. The sorted cells are then dropped onto
glass slides for H&E and eventually IHC and ISH staining. They have
dropped some cell suspension on to a plus-slide and air dried at 60
degrees C, then post-fixed in formalin and air dried again. The
morphology isn't very good and the cytoplasm doesn't show up at all on
H&E. Does anybody have a protocol for doing either cytospins (may not be
possible, only 2000 cells total!) or cell suspension dried slides to get
better morphology?

I believe they probably don't need heat to dry them. I also believe they
don't need an additional post-fix, but if they do one, to keep the slide
wet afterward (no additional air-drying step) and begin whatever
staining technique follows.

Thanks in advance for any suggestions!
