Invitrogen™ Human Calprotectin L1/S100-A8/A9 Complex ELISA Kit

Description

ELISA

Human Calprotectin L1/S100-A8/A9 Complex quantitates human Calprotectin L1/S100-A8/A9 Complex in serum, plasma, supernatant. The assay will exclusively recognize both natural and recombinant human Calprotectin L1/S100-A8/A9 Complex.

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.
