A synthetic peptide corresponding to amino acids 113-130 (PEIRKPEVLRPETPRPVD) of human caspase-9 was used as immunogen; GenBank no. gi|55960247|emb|CAI12974.1|.
This polyclonal antisera recognizes the proform of caspase-9 (~50 kDa), and the large (~35 kDa) subunit (with pro-domain sequences) of active/cleaved Caspase-9. It does not recognize the small (~15 kDa) subunit of active/cleaved Caspase-9. Intermediate caspase-9 cleavage forms may also be seen at ~21 kDa.

Apoptosis, or programmed cell death, is a common property of all multicellular organisms. The current dogma of apoptosis suggests that the components of the core cell-death machinery are integral to cells and widely conserved across species. Caspases, a family of cysteinyl aspartate-specific proteases, are integral components of the cell death machinery (reviewed in Siegal, 2006; and Lavrik et al, 2005). They play a central role in the initiation and execution of apoptotic cell death and in inflammation. Caspases are typically divided into 3 major groups, depending on the structure of their prodomain and their function. Group 1: inflammatory caspases (caspases 1, 4, 5, 11, 12, 14). Group II: initiator of apoptosis caspases (caspases 2, 8, 9). Group II: effector caspases (caspases 3, 6, 7). Caspases are synthesized as zymogens (inactive pro enzyme precursors which require a biochemical change to become active enzymes) with an N-terminal prodomain of variable length followed by a large subunit (p20) and a small subunit (p10). Caspases are activated through proteolytic cleavage at specific asparagine residues that are located within the prodomain, the p10, and p20 subunits. Activation results in the generation of mature active caspases that consist of the heterotetramer p202-p102. Active caspases mediate cell death and inflammation through cleavage of particular cellular substrates that are involved in these processes. The Caspase-9 polyclonal antisera recognizes the proform of caspase-9 (approx. 50 kDa), and the large (approx. 35 kDa) subunit (with pro-domain sequences) of active/cleaved Caspase-9. It does not recognize the small (approx. 15 kDa) subunit of active/cleaved Caspase-9.

Could I use HeLa cell lysate as a positive control for Caspase 9 primary antibodies in WB?
After looking through our testing it does appear you should be fine using HeLa as a positive control cell lysate for Caspase 9 in Western Blot, as we have used this sample successfully in our QC tests and shown expression of Caspase 9.
Caspase 3, the executioner of apoptosis Caspase-3 enzyme is a member of the family of endoproteases which regulate inflammation and apoptosis signaling networks. Caspase-3 is known as an executioner caspase in apoptosis because of its role in coordinating the destruction of cellular stru... Read full blog post.
Caspase 9 - an important apoptosis marker Caspases are essential mediators of programmed cell death and are needed for both the induction of apoptosis as well as for aiding the degradation of cellular structures.
