Background

Among the initiator caspases (caspases -2, -8 and -9), caspase-9 is an essential enzymes required for intrinsic or mitochondrial apoptotic pathway. Caspase 9 is a heterotetramer that consists of two anti-parallel arranged heterodimers, each one formed by a 35 kD (p35) and a 10 kD (p10) subunit, and it interacts with several proteins including APAF1, EFHD2, HAX1, BIRC2/c-IAP1, XIAP/BIRC4, BIRC5/survivin, BIRC6/bruce, BIRC7/livin etc. During apoptosome-dependent apoptotic execution, cytochrome-c is released from the mitochondria into cytosol where it binds/activates Apaf-1. Upon nucleotide exchange in the presence of dATP, Apaf-1 oligomerizes into heptameric apoptosome complex and procaspase-9 is recruited to apoptosome where it gets activated. Active caspase-9 at the apoptosome proteolytically activates procaspase-3 (the critical apoptotic executioner caspases) and cleaves poly(ADP-ribose) polymerase (PARP). Both caspases-9 and -3 can be inhibited by selected members of IAPs, with XIAP being their most potent natural inhibitor. Phosphorylation of a major site, Thr125 by CDK1-cyclin B1 leading to inhibition of caspase 9 plays a critical role in the restraint of apoptosis during mitotic arrest. This site is also targeted by ERK1/2 in response to growth factor signalling and by DYRK1A, which plays important roles during development.

FAQs for Caspase-9 Antibody (NB500-209). (Showing 1 - 2 of 2 FAQs).

1. 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.
2. Does NB500-209 both recognize human and rat active form of caspase 9 (subunit p35 or subunit p10)? Besides that please let me know if NB500-209 also recognize pro-form caspase 9?
   • Caspase 9 Antibody (LAP6 96-2-22) # NB500-209 is human specific and do not recognize rat samples. It is expected to detect pro as well as activated form of caspase 9. In our QC data using 293 cell lysates, we observed active subunit p35 only not subunit p10. Both of these antibodies were tested on lysates of 293 cells of human origin (also called Human Embryonic Kidney 293 cells). We did not validate them on rat samples as the antibodies are Human specific.
