We are interested in counting the number of cells expressing various
cytokines in a mouse model using flow cytometry. The only published work
I've seen looking at intracellular cytokines and flow was in vitro
stimulation in the presence of a protein transport inhibitor.
Do any of you have experience detecting intracellular cytokines from in vivo
experimental sytems (such as mouse blood or spleen cells) by flow? Is it
reasonable to expect to be able to get anti-cytokine antibody molecules into
a cell without the cytokines leaking out? (I assume a fixation step would
have to preceed the permeablization step.) I'd appreciate any information
about, or directions to, a protocol which works.
Thanks in advance.
