生理活性
One unit of the recombinant caspase-4 is the enzyme activity that cleaves 1 nmol of the caspase substrate WEHD-pNA (pNA: pnitroanaline) per hour at 37°C 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.

備考
This product is manufactured by BioVision, an Abcam company and was previously called 1084 Caspase-4, human recombinant. 1084-100 is the same size as the 100 unit size of ab51994.
This protein is a heterotetramer consisting of two large and two small subunits. Active Caspase 4 is useful in studying enzyme regulation, determining target substrates, screening caspase inhibitors, or as a positive control in caspase activity assays.
5000 units/mg.
