Rapid Cell Count (in vivo) - (Nov/27/2009 )

Hello

i'm looking for a method to count cells (HeLa, NIH..) in vivo, i.e. i would like to take only an aliquot of the culture, analyze them and know how many are in the aliquot. Cause there are a lot of samples which i have to process at the same time, i would highly appreciate if its a really easy and rapid method, because if its going too long then an error can occur or precision isnt given anymore, respectively.

Thanks & Cheers, wish you nice weekend

FACS?

...or perhaps something like the Invitrogen Countess or Beckmann Coulter X-Cell.
