Description générale
Specificity: Caspase-3 (also known as CPP32, Yama and apopain) is a member of the interleukin-1beta converting enzyme (ICE) family 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) granzyme B. The processed form of caspase-3 consists of large (17 kDa) and small (12 kDa) 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 partially purified* active recombinant human caspase-3 protein with full-length His-6 tag was expressed in E. coli. The expressed Caspase-3 spontaneously undergoes autoprocessing to yield the subunits characteristic of the native enzyme. The recombinant caspase-3 preferentially cleaves caspase-3 substrates (e.g., DEVD-AFC or DEVD-pNA). In combination with caspase-3 activity assays, the active recombinant caspase-3 is very useful in the biological screening of caspase inhibitors. The recombinant enzyme can also be used as a positive control in caspase assays or in determining the specificity of caspase substrates.
*10-25% caspase-3 protein by gel analysis, also contains E. Coli proteins. Approximately, 0.8-2 μg total protein / unit of activity. GenBank # U13737.

Application
Western blot: 1-5 μL of stock per lane. Protein is full length caspase 3 with His-Tag. It is autoactivated thus active caspase subunits will be seen
and 17kDa + 12kDa (large and small subunits) can be seen depending upon the antibody. Small subunit is extremely difficult to detect in most westerns. The size of inactive enzime is ~32 kDa.
Activation: Not needed. When expressed in E. coli, caspase-3 spontaneously undergoes autoprocessing to yield the subunits characteristic of the active enzyme.

Définition de l'unité
Specific Activity: One unit of the recombinant caspase-3 is the enzyme activity that cleaves 1 nmol of the caspase substrate DEVD-pNA (pNA: pnitroanaline) per hour at 37°C at saturated substrate concentrations.

Necrostatin-1 inhibits receptor-interacting protein (RIP)-1 kinase and programmed necrosis and is neuroprotective in adult rodent models. Owing to the prominence of necrosis and continuum cell death in neonatal hypoxia-ischemia (HI), we tested whether necrostatin was neuroprotective in the developing brain.
