Active Recombinant Human CASP9 protein

• Cat.No.: CASP9-49H
• Product Overview: Recombinant Human CASP9 was expressed in E. coli.

Specification

• Species: Human
• Source: E.coli
• Tag: Non
• Description: 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.
• Form: Lyophilized powder
• Bio-activity: > 400 units/mg
• Purity: ≥90%
• Unit Definition: 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 centigrade 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.
• Applications: 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.
• Notes: Centrifuge the vial prior to opening.
• Storage: The lyophilized caspase-9 is stable for 1 year at –70 centigrade. Following reconstitution in PBS, the enzyme should be aliquoted and immediately stored at –70 centigrade. Avoid multiple freeze/thaw cycles as activity might decrease.
• Reconstitution: Reconstitute to 1 unit per μl in PBS containing 15% glycerol.
