One unit of the recombinant caspase-9 is the enzyme activity that cleaves 1 nmol of the caspase substrate LEHD-pNA (pNA: pnitroanaline) per hour at 37°C in a reaction solution containing 50 mM Hepes, pH 7.2, 50 mM NaCl, 0.1% Chaps, 10 mM EDTA, 5% Glycerol, and 10 mM DTT.
FORM: Lyophilized powder
RECONSTITUTION: Reconstitute to 1 unit per l in PBS containing 15% glycerol.
SPECIFIC ACTIVITY: 400 units/mg
PURITY: >90% by SDS-PAGE
The lyophilized caspase-9 is stable for 1 year at –70°C. Following reconstitution in PBS, the enzyme should be aliquoted and immediately stored at –70°C. Avoid multiple freeze/thaw cycles as activity might decrease.
Caspase-9 is a member of the caspase-family of cysteine proteases. Similar to other caspases, caspase-9 also exists in cells as an inactive proenzyme. During the initiation of apoptosis procaspase-9 is processed at aspartate residues to form active caspase-9. As one of the initiator caspases, active caspase-9 functions to trigger activation of downstream effector caspases, leading to disassembly of cell structures.
The recombinant active human caspase-9 was expressed in E. coli. The active caspase-9 is routinely tested at BioVision for its ability to enzymatically cleave these two substrates Ac-LEHD-pNA (Cat. #1076-200) or Ac-LEHD-AFC (1075-200).
APPLICATIONS AND USAGE:
Active caspase-9 is useful in studying enzyme regulation, determining target substrates, screening caspase inhibitors, or as a positive control in caspase activity assays. We recommend using 1 unit/assay for analyzing caspase activity.
