S-100 protein is a family of low molecular weight protein characterized by two calcium binding sites of the helix-loop-helix ("EF-hand type") conformation. There are at least 21 different types of S100 proteins. This antibody is specific for beta subunit of S-100 protein. S-100 protein has been found in normal melanocytes, Langerhans cells, histiocytes, chrondrocytes, lipocytes, skeletal and cardiac muscle, Schwann cells, epithelial and myoepithelial cells of the breast, salivary and sweat glands, as well as in glial cells. This antibody detects neoplasms derived from these cells, a large number of tumors of the salivary gland, adipose and cartilaginous tissue, Schwann cell derived tumors, and almost all malignant melanomas and cases of histiocytosis x. Despite the fact that S-100 protein is an ubiquitous substance, its demonstration is of great value in the identification of several neoplasms, particularly melanomas.
