S-100 from bovine brain

General description

The S-100 protein family consists of around 16 calcium binding proteins that have distinct tissue specific expression patterns. S-100 proteins are widely expressed in neural and non-neural cell types, as well as in several cancers. These proteins regulate a broad range of cellular functions such as cell growth, signaling, cell structure, and energy metabolism . In immunohistology, the product specifically stains the S-100 protein. The product binds to S-100 protein in human, rat, guinea pig, and bovine. In the brain, the antibody can be used to stain glial and ependymal cells, as well as Schwann cells of the peripheral nervous system. In the skin, melanocytes and Langerhans cells can be stained by the antibody product. In lymph nodes, interdigitating reticulum cells are positively stained by anti-S-100 antibody. S-100 staining can be observed in almost all human benign and malignant melanocytic tumors.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.


Anti-S-100 antibody is suitable for use in microarray, and immunohistochemistry (in formalin-fixed, paraffin-embedded sections, or using a conc. of 20-100 μg/mL in sections of human or rat cerebellum). The antibody may also be used in immunoelectrophoresis.
