Hi,
I isolate/culture mouse splenocytes in the following way:
Mash spleen through a cell strainer (40 micron mesh) in PBS, lyse red
blood cells with NH4Cl and put in culture in DMEM with 10% FBS.
Trypan Blue immediately after the isolation gives viabilities better
then 85% - 90%, but after 24 hr culture the viability has gone down to
30% - 50%.
I need the splenocytes "untouched' in flow cytometry studies, i.e., I
cannot stimulate with things like ConA.
I tried a whole bunch of things with cell density, culture additives,
incubation temp, etc, without much avail.
Does anybody know how to improve this?
Thanks for your input!
