Protein activity determined to be > 5000 units/mg. One unit of the recombinant caspase-5 is the enzyme activity that cleaves 1 nmol of the caspase substrate WEHD-pNA (pNA: pnitroanaline) per hour at 37ºC 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.
Reconstitute to 1 unit per μl in PBS containing 15% glycerol. Store at -80ºC.
Purity was assessed by SDS-PAGE (≥95%) and by HPLC.

Caspase-5 (also know as ICErelIII, TY) is a member of the caspase-family of cysteine proteases. Similar to other caspases, caspase-5 exists in cells as an inactive proenzyme which is matured by proteolysis to yield large and small subunits. The active caspase-5 is a heterotetramer consisting of two large and two small subunits. To date the mechanism of caspase-5 activation and roles of caspase-5 in apoptosis are poorly understood.
