Granzyme B (GZMB) is a serine protease stored in granules of activated cytotoxic T cells and NK cells. Upon target cell contact, granzyme B is directionally exocytosed and assisted by perforin, enters the target cell. With its unique substrate specificity (granzyme B cleaves after Asp), granzyme B processes and activates various pro-caspases thereby inducing apoptosis in the target cell.||Source:|Recombinant corresponding to human Granzyme b expressed in insect cells.||Molecular Weight:|~32kD||Biological Activity:|Activity of GZMB was tested using the synthetic peptide, IETD-AFC, as a substrate. GZMB releases AFC and then the GZMB activity can be quantified by fluorescent detection of free AFC at Ex/Em=380/500nm.||Storage and Stability:|Lyophilized powder may be stored at -20°C. Stable for 12 months at -20°C. Reconstitute with sterile buffer. Aliquot to avoid repeated freezing and thawing. Store at -20°C. Reconstituted product is stable for 6 months at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
