产品概述
Abcam’s Granzyme B (CTLA-1) Human in vitro ELISA (Enzyme-Linked Immunosorbent Assay) kit is designed for the quantitative measurement of Granzyme B in Human serum, plasma, buffered solutions and cell culture medium.
A monoclonal antibody specific Granzyme B has been coated onto the wells of the microtiter strips provided. Samples, including standards of known Granzyme B concentrations, control specimens or unknowns are pipetted into these wells. During the first incubation, the standards or samples and a biotinylated monoclonal antibody specific for Granzyme B are simultaneously incubated. After washing, the enzyme Streptavidin-HRP, that binds the biotinylated antibody is added, incubated and washed. A TMB substrate solution is added which acts on the bound enzyme to induce a colored reaction product. The intensity of this colored product is directly proportional to the concentration of Granzyme B present in the samples.
This kit will recognize both endogenous and recombinant Human Granzyme B.

The lytic enzymes of cytotoxic lymphocytes seem to be contained within lysosome-like granules found in the cytoplasm. These granules contain perforin, a membrane pore-forming protein, and a family of serine proteases (granzymes). Granzyme B, a 32 kDa protein, is a serine Aspase associated with the granules of Natural Killer (NK) cells. Granzyme B seems to be able to elicit cell death, perhaps by activating an endogenous pathway of programmed cell death. -
