Cat no: 167844

Granzyme B Activity BioAssay(TM) Kit (Fluorometric)

Granzyme B (GZMB, EC number 3.4.21.79) also known as Granzyme-2 is a serine protease stored in the granules of activated cytotoxic T cells and NK cells. Upon target cell contact, Granzyme B is directionally exocytosed and with the assistance of perforin enters the target cell. With its unique substrate specificity (Granzyme B prefers an aspartic acid residue at the P1 site of its substrates), Granzyme B processes and activates various pro-caspases thereby inducing apoptosis in the target cell. \n\nIntended Use:\nMeasurement of Granzyme B activity in various biological samples or purified Granzyme B activity, Screening Granzyme B inhibitors, characterize/Study Granzyme B inhibitors.\n\nTest Principle:\nIn the Granzyme B Activity BioAssay(TM) Kit, active human Granzyme B enzyme hydrolyzes the specific substrate to release the quench of fluorescent group, which can be detected fluorometrically at Ex/Em = 380/500nm. This BioAssay(TM) kit is rapid, reliable and sensitive and can detect Granzyme B activity in various biological samples.\n\nKit Components:\nGranzyme B Assay Buffer, 1x25ml\nGranzyme B Substrate, 1x0.5ml\nPositive Control, Granzyme B Enzyme, human recombinant, 1x vial\nAFC Standard, 1mM, 1x0.1ml\n\nStorage and Stability:\nStore powder at 4 degrees C liquid at -20 degrees C. Store other components at 4 degrees C. Stable for at least 6 months For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
