GZMB Activity Fluorometric Assay Kit

Cat.No.: Kit-0403
Product Overview: GZMB Activity Assay Kit (Fluorometric) is used for measuring granzyme B activity using fluorometric methods.
Description: 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. In GZMB Activity Assay Kit (Fluorometric), we have utilized a peptide substrate containing the Granzyme B recognition sequence along with a fluorescent label "AFC". Granzyme B catalyzes the cleavage of this substrate and releases the AFC molecule, which can be detected fluorometrically (Ex/Em = 380/500 nm). This Assay Kit is rapid, reliable and sensitive and can detect Granzyme B activity in various biological samples.
Applications: Measurement of Granzyme B activity in various biological samples or purified Granzyme B activity.Study & characterize Granzyme B inhibitors.
Usage: For research use only (RUO)
Storage: Store kit at -20°C, protected from light. Warm Assay Buffer to room temperature before use. Briefly centrifuge small vials prior to opening.
