Product Information
KE00121 is a solid phase sandwich Enzyme Linked-Immuno-Sorbent Assay (Sandwich ELISA). The Granzyme B ELISA kit is to be used to detect and quantify protein levels of endogenous Granzyme B. The assay recognizes human Granzyme B. An antibody specific for Granzyme B has been pre-coated onto the microwells. The Granzyme B protein in samples is captured by the coated antibody after incubation. Following extensive washing, another antibody of biotinylated specific for Granzyme B is added to detect the captured Granzyme B protein. For signal development, Streptavidin-HRP is added, followed by Tetramethyl-benzidine (TMB) reagent. Solution containing sulfuric acid is used to stop color development and the color intensity which is proportional to the quantity of bound protein is measurable at 450 nm with the correction wavelength set at 630 nm.

Background Information
Granzyme B (GZMB) is also named as CGL1, CSPB, CTLA1, GRB and belongs to the Granzyme subfamily. This enzyme is necessary for target cell lysis in cell-mediated immune responses. The cytotoxic lymphocyte protease Granzyme B (GZMB) can promote apoptosis through direct processing and activation of members of the caspase family. Granzyme B also functions as processing protease of cytokines, including interleukin (IL)-18 and IL-1a, and extracellular matrix proteins, including fibronectin and various proteoglycans. Plasma Granzyme B concentrations were significantly higher in patients with Atopic dermatitis (AD) and psoriasis than in healthy controls, which indicated that Granzyme B may play an important role in the induction of intractable itch and dermatitis in AD.
