I have been using a Cleaved (activated) Caspase-3 ab from Cell Signaling.
This one has definitely outperformed the Promega one I used to use. I have
used the Cell Signaling Caspase on FFPE sections as well as Western blots,
where it also works. The Promega Caspase-3 is not recommended for Westerns.
Hope this helps,
