Monoclonal Anti-Granzyme B antibody is suitable for western blot and immunocytochemistry at a dilution of 1:20 using pretreated tissues.

Biochem/physiol Actions

Granzyme B, neutral serine protease, is expressed in cytoplasmic granules of activated cytotoxic T lymphocytes and natural killer cells. It contains a leader sequence (cleaved by a signal peptidase) and two amino acid prodomains (cleaved by the lysosomal cysteine protease DPPI). It plays a major role in the caspase dependent apoptotic pathway by activating most of the caspases in vitro and in vivo. It cleaves the aspartic acid residues, to facilitate cell death by various pathways. It has been shown that granzyme B has capacity to facilitate cytochrome C release from the mitochondria in a caspase independent way.

Physical form

Supplied in serum-free culture medium containing 1% bovine serum albumin and 0.1% sodium azide.

CD8+ cytotoxic lymphocytes, natural killer cells and lymphokine-activated killer cells depend primarily on the perforin/granzyme system to kill their targets, while CD4+ T cells utilize Fas and other mechanisms to induce cell death. The molecular mechanisms used by these pathways

Viral strategies for escaping apoptosis have co-evolved with the immune system, resulting in a complex balance of pro- and anti-apoptotic forces in virus-infected cells under attack by cytotoxic T lymphocytes (CTLs). Here, Joseph Trapani and colleagues argue that CTL cytolytic
