Product name : Active Human Caspase_310 ug
Catalog number : 1083-10

FORM: Lyophilized powder
RECONSTITUTION: Reconstitute in PBS containing 15% glycerol.
The lyophilized caspase-3 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-3 (also know as CPP32, Yama and apopain) is a major member of the caspasefamily of cysteine proteases. Caspase-3 exists in cells as an inactive 32 kDa proenzyme.
During apoptosis procaspase-3 is processed at aspartate residues by self-proteolysis and/or cleavage by upstream caspases, such as caspase-6 (Mch2), caspase-8 (Flice) and grazyme B. The processed form of caspase-3 consists of large (17 kD) and small (11 kD) subunits which associate to form the active enzyme. The active caspase-3 has been shown involving in the proteolysis of several important molecules, such as poly (ADP-ribose) polymerase (PARP), the sterol regulatory element binding proteins (SREBPs), focal adhesion kinase (FAK), and others. The recombinant active human caspase-3 expressed in E. coli spontaneously undergoes autoprocessing to yield subunits characteristic of the native enzyme (Full length gene Accession No. NP_004337) . The active caspase-3 preferentially cleaves caspase-3 substrates (e.g., DEVD-AFC or DEVD-pNA) and is routinely tested at BioVision for its ability to enzymatically cleave these two substrates Ac-DEVD-pNA (Cat.#1008-200) or Ac-DEVD-AFC (1007-200).
APPLICATIONS AND USAGE:
Active caspase-3 is useful in studying enzyme regulation, determining target substrates, screening caspase inhibitors, or as a positive control in caspase activity assays and Western blot analysis.
