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 = 380/500 nm.
Reconstitution Instructions Use 50 µl sterile D.I. water to dissolve 5 µg protein to a final conc of 0.1 µg protein/µl.
Handling Centrifuge the vial prior to opening.
Storage Conditions -70°C
Shipping Conditions Dry Ice
USAGE For Research Use Only! Not to be used in humans


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 enters the target cell, assisted by perforin. 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.
