Target Information

The S100A8/A9 heterocomplex, also called MRP-8/MRP-14 complex or calprotectin, comprises 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 only intracellularly.
The S100A8/A9 complex exhibits antibacterial, antifungal, immunomodulating, and antiproliferative effects and serves as a potent chemotactic factor for neutrophils.
Plasma concentrations are elevated in diseases with increased neutrophil activity, such as inflammatory bowel disease.
Calprotectin is detectable in feces due to granulocyte transmigration through the intestinal wall. Elevated levels have also been observed in plasma, saliva, gingival crevicular fluid, stools, and synovial fluid during infection and inflammatory conditions.
