I like the cell signaling antibody also, I tried biocare's but did not have much success with it. The cell signaling antibody also works with pronase digestion, as well as the EDTA pH9 HIER. We have even used it on bone sections with the pronase digestion. Works in multiple species, I have used it on human, rat, mouse, guinea pig, porcine and canine. Our protocol is similar to Cheryl's. It’s a bit pricy as antibodies go, but I feel its worth it. Good lot to lot consistency. We have probably gone through about 5 different lots, with not changing the protocol at all. I have a written protocol if anyone is interested.

Subject: Re: [Histonet] IHC anti-cleaved caspase 3
I will second the Cell Signaling antibody - we have tried antibodies from Promega (which gave tons of background staining)...then via this site i was pointed to Cell Signaling's monoclonal which we tried; the polyclonal actually has been working very well with minimal background (we were getting lots of respiratory epithelium and endothelium lighting up in control animals). I have been using it in mice with this protocol:
EDTA with PASCAL
primary antibody 60 minutes, dilution 1:125 Rabbit envision DAB plus
Hope this helps!
