Background: Caspase-9

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) and small (approx. 15 kDa) subunits of active/cleaved Caspase-9.

FAQs for Caspase-9 Antibody - BSA Free

Showing  1 - 1 of 1 FAQ Showing All

  • Q: Could I use HeLa cell lysate as a positive control for Caspase 9 primary antibodies in WB?

    A: 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.
