Granzyme B Polyclonal, anti-human

Description: Granzyme B is a member of the granule serine protease family stored specifically in NK cells or cytotoxic T cells. Cytolytic T lymphocytes (CTL) and natural killer (NK) cells share the 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. Granzyme B is crucial for the rapid induction of target cell apoptosis by CTLs in the cell-mediated immune response. Granzyme B is useful as a marker in the identification of T/NK-cell lymphomas in conjunction with CD56Localization: cytoplasm granuleDilution: 50-200Positive Control: tonsil, Hodgkin's lymphomaHIER: citrate pH6.0 or EDTA pH8.0Status: RUO
