Anti-Mouse Granzyme B Purified

Description: 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.
