James I to recommend the rab mono ki67 from Labvision and for CC3 although I
have used the rab one from Cell Signaling and it works, I now get rab CC3
from BioCare it works as well in my hands and is much cheaper.  As Chris
says, I would use formalin fixation on frozens for these two markers.

James,Go for rabbit monoclonal clone SP6 (Thermo, Vector) for Ki67 antibody
that and rabbit anti-caspase-3 antibody from Cell Signalling. Both
antibodies works on many different species.Your cryostat tissue section from
fresh frozen blocks should be well dried (overnight, RT, under a fan) and
fixed in NBF for 5 min at RT. Acetone-fixation makes your positive nuclei
very blurry and diffuse. Wash 3-4x with TBS (or PBS) and start your
immuno.Cheers, ChrisChris van der Loos, PhD Dept. of Pathology Academic

I would like to measure both proliferation and apoptosis. Can  anyone
recommend a good Ki-67 antibody of use on fresh frozen tissue to measure
proliferation and an antibody for activated caspase 3 for apoptosis on mouse
tissue. Please not fixation used if possible. I apologize for the confusion
with my previous e-mail.
Thank you,
