Granzyme B Rat anti-Mouse, Clone: 16G6, eBioscience, Rat Monoclonal Antibody, Each

Details

: The 16G6 antibody reacts with mouse Granzyme B (GrB) which is a member of the granzyme serine protease family. GrB 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. GrB has been called 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. GrB 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. For intracellular staining and flow cytometric analysis with direct conjugates of anti-mouse Granzyme B, it is highly recommended to use the Foxp3 Staining Buffer Set (cat. 00-5523). Other buffers may yield varying results. For more information, please contact technical support at tech@ebioscience.com. Applications Reported: This 16G6 antibody has been reported for use in western blotting, immunohistochemical staining, ELISA capture antibody, and immunohistochemical staining of formalin-fixed paraffin embedded tissue sections.Applications Tested: The unlabelled 16G6 antibody has been tested as the capture antibody in a sandwich ELISA for quantitation of mouse granzyme B protein levels, in combination with the biotinylated eBioLUEE (13-8821) antibody for detection and recombit mouse granzyme B as the standard. A suitable range of concentrations of this antibody for ELISA detection is 1-4 µg/mL. The 16G6 antibody has been tested for Western blotting; a recommended starting concentration is 1 µg/mL. The 16G6 antibody has been used for formalin-fixed paraffin embedded tissue using low pH antigen retrieval at less than or equal to 20 µg/mL. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest. Purity: Greater than 90%, as determined by SDS-PAGE. Aggregation: Less than 10%, as determined by HPLC. Filtration: 0.2 μm post-manufacturing filtered.

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.
