Anti-Caspase 3 Antibody is suitable for use in IHC (frozen), IHC (paraffin), and WB. Expect a band approximately 31.5 kDa on specific lysates. The antibody detects both pro Caspase-3(32 kDa) and the large subunit of the active/cleaved form (14-21 kDa) of Caspase-3. The large subunit of the cleaved form may appear as one or two or even as a stack of bands depending on the presence or absence of the Caspase-3 pro-domain. Specific conditions for reactivity should be optimized by the end user.
