Calprotectin Monoclonal Antibody (27E10), Biotin, Invitrogen™

Description

MA1-40314 detects Calprotectin from human and non-human primate samples. Does not cross react with mouse. MA1-40314 has been successfully used in ELISA, immunohistochemistry (frozen), flow cytometry, immunofluorescence, immunoprecipitation and Western blot applications. For Western blot, detects the non-reduced protein at about 22 kDa. The MA1-40314 immunogen is proprietary.

The S100A8/A9 heterocomplex, also called MRP-8/MRP-14 complex or calprotectin, comprises 60% of the cytoplasmic protein fraction of circulating polymorphonuclear granulocytes and is also found in monocytes, macrophages and ileal tissue eosinophils. Peripheral blood monocytes carry the antigen extra- and intracellularly, neutrophils only intracellularly. The S100A8/A9 complex has antibacterial, antifungal, immunomodulating and antiproliferative effects. Besides this it is a potent chemotactic factor for neutrophils. Plasma concentrations are elevated in diseases associated with increased neutrophil activity, like inflammatory bowel disease. Granulocytes terminate their existence after transmigration through the intestinal wall. Therefore calprotectin is also detectable in feces. Elevated levels of calprotectin have been observed in body fluids such as plasma, saliva, gingival crevicular fluid, stools, and synovial fluid during infection and inflammatory conditions.
