Invitrogen™ Granzyme A Monoclonal Antibody (GzA-3G8.5), PE, eBioscience™

Description

Description: This Gza-3G8.5 monoclonal antibody reacts with mouse Granzyme A. Granzyme A is the most abundantly expressed of the ten granzyme serine proteases that have been identified in mice. Granzymes are proteins released from the granules of NK cells and cytotoxic T lymphocytes that induce death in target cells by cleavage of intracellular substrates and play a critical role in immune defense against viruses, tumors, and intracellular bacteria. Granzyme A activates caspase-independent cell death pathways morphologically similar to apoptosis and characterized by mitochondrial and DNA damage. It may also play a role in inflammation, as the precursor form of IL-1 beta (pro-IL-1 beta) is among its target substrates. Granzyme A shares overlapping substrate specificity with the closely-related Granzyme K, which is believed to account for the minimal decrease in cytotoxicity of Granzyme A-deficient CTLs. Applications Reported: This GzA-3G8.5 antibody has been reported for use in intracellular staining followed by flow cytometric analysis. Applications Tested: This GzA-3G8.5 antibody has been tested by intracellular staining and flow cytometric analysis of stimulated mouse splenocytes using the Intracellular Fixation & Permeabilization Buffer Set (Product # 88-8824-00) and protocol. Please refer to BestProtocols®: Protocol A: Two step protocol for (cytoplasmic) intracellular proteins located under the Resources Tab online. This antibody can be used at less than or equ...

Cytolytic T lymphocytes (CTL) and natural killer (NK) cells share the remarkable ability to recognize, bind, and lyse specific target cells. They are thought to protect their host by lysing cells bearing on their surface 'nonself' antigens, usually peptides or proteins resulting from infection by intracellular pathogens. The protein described here is a T cell- and natural killer cell-specific serine protease that may function as a common component necessary for lysis of target cells by cytotoxic T lymphocytes and natural killer cells.
