AffiAB® Anti-S100A9 Antibody [JF096-8]

The family of EF-hand type Ca²⁺-binding proteins includes Calbindin (previously designated vitamin D-dependent Ca²⁺-binding protein) , S-100α and β, Calgranulin A (also designated MRP8) , Calgranulin B (also designated MRP14) and Calgranulin C (S-100 like protein) , and the parvalbumin family members, including parvalbumin α and parvalbumin β (also designated oncomodulin) . Calbindin, S-100 proteins and parvalbumin proteins are each expressed in neural tissues. In addition, S-100α and β are present in a variety of other tissues, and Calbindin is present in intestine and kidney. Parvalbumin α is also found in fast-contracting/relaxing skeletal muscle fibers and parvalbumin β is found in many tumor tissues as well as in the organ of Corti. Calbindin, S-100 proteins and parvalbulmins have all been detected in leydig cells and testis. These proteins are thought to play a role in hormone production and spermatogenesis. Calgranulin is expressed in macrophages and epithelial cells.
