Application

Granzyme B Substrate (Ac-IEPD-AMC) is a fluorogenic substrate for the detection and assay of caspase 8 and granzyme B which is involved in the rapid induction of target cell apoptosis by CTL in cell-mediated immune response.

Biochem/physiol Actions

Granzymes belongs to serine proteinase family enzymes and it localizes along with perforin in granules. It is predominant in cytotoxic T cells. Granzyme B induces caspases dependent and independent cell death. It possesses specific cleavage action at aspartate residue in the substrate.

Cytotoxic T lymphocytes (CTLs) are the major killer of virus-infected cells. Granzyme B (GrB) from CTLs induces apoptosis in target cells by cleavage and activation of substrates like caspase-3 and Bid. However, while undergoing apoptosis, cells are still capable of
