Granzyme B Monoclonal Antibody (NGZB), PE-Cyanine7, eBioscience™, Invitrogen™

Description

• Description: This NGZB monoclonal antibody reacts with mouse Granzyme B, which is a member of the granzyme serine protease family
• Granzyme B is found in the granules of cytotoxic T cells and NK cells
• Granzyme B has also been described as CGL1 (cathepsin G-like-1), a serine protease expressed only in cytotoxic T-lymphocytes after cell activation, and CTLA-1 (cytotoxic T lymphocyte-associated serine esterase 1) based on identification of mRNA in various cytotoxic T cells, but not observed in non-cytotoxic lymphoid cells
• Granzyme B is crucial for the rapid induction of target cell death by apoptosis, induced by interaction with cytotoxic T cells
• The receptor involved has been identified as mannose 6-phosphate receptor
• This receptor functions as a death receptor for Granzyme B during cytotoxic T cell-induced apoptosis
• This NGZB monoclonal antibody does not crossreact to human Granzyme B nor is staining blocked with GB11, suggesting it recognizes a different epitope
• Applications Reported: This NGZB antibody has been reported for use in intracellular staining and flow cytometric analysis
• Applications Tested: This NGZB antibody has been tested by intracellular staining and flow cytometric analysis of mouse splenocytes using the Intracellular Fixation & Permeabilization Buffer Set (cat
• 88-8824) and protocol
• Please refer to Best Protocols: Protocol A: Two step protocol for (cytoplasmic) intracellular proteins
• This can be used at less than or equal to 0
• Granzyme B is a member of the granzyme serine protease family, and is found in the granules of cytotoxic T cells and NK cells
• Granzyme B has been described as CGL1 (cathepsin G-like-1), a serine protease expressed only in cytotoxic T-lymphocytes after cell activation, and CTLA-1 (cytotoxic T lymphocyte-associated serine esterase 1) based on identification of mRNA in various cytotoxic T cells, but not observed in non-cytotoxic lymphoid cells
• Granzyme B is crucial for the rapid induction of target cell death by apoptosis, induced by interaction with cytotoxic T cells
• The receptor involved in this process has been identified as mannose 6-phosphate receptor which functions as a death receptor for Granzyme B during cytotoxic T cell-induced apoptosis
• Granzyme B enters target cells to cleave caspase-3 and initiate the caspase cascade leading to DNA fragmentation and apoptosis
• Granzyme B can also act through a mitochondrial apoptosis pathway by cleaving the Bid protein
• Granzymes are neutral serine proteases, which are stored in specialized lytic granules of cytotoxic T lymphocytes (CTLs) and in natural killer (NK) cells
• A number of granzymes (A to G) have been isolated and cloned from mouse CTLs and NK cells, however in man, fewer have been cloned and identified.
