Alternative Name: | CPP32, Yama, Apopain |
Source: | Produced in E. coli. Contains an N-terminal His-tag. |
EC: | 3.4.22.56 |
UniProt ID: | P42574 |
Formulation: | Lyophilized. |
Quality Control: | Routinely tested for its ability to cleave the caspase-3 substrates Ac-DEVD-pNA (Prod. No. ALX-260-033) and Ac-DEVD-AFC (Prod. No. ALX-260-032). |
Specific Activity: | ≥15,000 U/mg protein. One unit is defined as the amount of enzyme that cleaves 1nmol of the caspase substrate DEVD-pNA (Prod. No. ALX-260-033) per hour at 37°C in a reaction solution containing 50mM HEPES, pH 7.2, 50mM NaCl, 0.1% CHAPS, 10mM EDTA, 5% glycerol and 10mM DTT. |
Application Notes: | Useful in studying enzyme regulation, determining target substrate, screening caspase inhibitors, or as a positive control in caspase assays. We recommend using 1 unit per assay for analyzing caspase activity. For a complete caspase-3 assay protocol, please refer to Caspase-3 Fluorometric or Colorimetric Assay Kits (Prod. No. ALX-850-216 or ALX-850-215). |
Reconstitution: | Reconstitute to 1U/µl with PBS containing 15% glycerol. |
Shipping: | Shipped on Dry Ice |
Long Term Storage: | -80°C |
Handling: | Avoid freeze/thaw cycles. After reconstitution, prepare aliquots and store at -80°C. |
Scientific Background: | Caspase-3 is a member of the interleukin-1β converting enzyme (ICE) family of cysteine proteases. It exists in cells as an inactive 32kDa proenzyme. During apoptosis procaspase-3 is processed at aspartate residues by self-proteolysis and/or cleavage by upstream caspases, such as caspase-6, caspase-8 and granzyme B. The processed form of caspase-3 consists of large (17kDa) and small (11kDa) subunits which associate to form the active enzyme. Active caspase-3 has been shown involved 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.
