Target Information
The S100A8/A9 heterocomplex, also known as MRP-8/MRP-14 complex or calprotectin, constitutes about 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 both extra- and intracellularly, while neutrophils carry it only intracellularly.
The S100A8/A9 complex exhibits antibacterial, antifungal, immunomodulating, and antiproliferative effects, and acts as a potent chemotactic factor for neutrophils.
Elevated plasma concentrations are associated with diseases involving increased neutrophil activity, such as inflammatory bowel disease.
Calprotectin can also be detected in feces, and elevated levels have been observed in plasma, saliva, gingival crevicular fluid, stools, and synovial fluid during infection and inflammatory conditions.
