Description: Caspase 9 (ICE-LAP6, Mch-6, Apaf-3) is a member of a family of cysteine proteases which play a critical role in the induction of programmed cell death. Members of this family have been grouped according to sequence homology as being either ICE-like proteases (caspases 1, 4 and 5) or Ced-3- like proteases (caspases 3, 6, 7, 9 and 10a). Caspase-9 is produced as a 48 kD precursor (procaspase-9) which contains an N-terminal prodomain with high homology to caspase-2. Procaspase-9 may be processed into subunits which heterodimerize to form the active enzyme. Activation of caspase-9 occurs in the presence of cytochrome c (Apaf-2), following an interaction between caspase-9 and Apaf-1. Activation may also be triggered directly by the cytotoxic T-cell protease, granzyme B. Active caspase-9 cleaves and thus activates caspase-3 and is also a relevant target of active caspase-3. Caspase- 9 can also cleave the nuclear protein PARP. Northern blot analysis suggests that high expression of caspase-9 is found in the heart, testis and ovary.

Characteristics: 1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
2. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
3. Please refer to us for technical protocols.
