NA.41

S-100 (β-Subunit) is a calcium-binding protein, that belongs to S100 family of calcium-binding proteins. It is expressed in melanocytes. It is located on human chromosome 21q22.3.
Monoclonal Anti-S-100 (b-Subunit) (mouse IgG1 isotype) is derived from the SH-B4 hybridoma produced by the fusion of mouse myeloma cells and splenocytes from immunized BALB/c mice. S-100 is a set of small, highly acidic, thermolabile dimer proteins of ~20 kDa, widely distributed in different tissues.

Recognizes an epitope located on the β chain (i.e. in S-100a and S-100b) but not on the α chain of S-100 (i.e. in S-100a and S-100ao). In ELISA, recognition of S-100 subunit by clone SH-B4 is Ca²⁺-dependent. The product does not react with other members of the EF-hand family such as, calmodulin, parvalbumin, intestinal calcium-binding protein and myosin light chain. In immunohistochemistry, the antibody detects normal and neoplastic S-100 β subunit-containing cells (e.g. Schwann cells, chondrocytes, melanocytes, and melanotic tumors) in protease-digested, formalin-fixed, paraffin-embedded tissues.

Immunocytochemistry (1 paper)
Monoclonal Anti-S-100 (β-Subunit) antibody produced in mouse has been used in immunocytochemistry and immunohistochemistry. It has also been used as a component in serum medium for 5-ethynyl-29-deoxyuridine (EdU), incorporation assay.

S-100 is considered to be a cell-growth regulator, but other functions have been suggested, e.g., increasing the membrane permeability to cations under physiologic conditions, stimulation of nucleolar RNA polymerase activity, interaction with the tumor suppressor protein p53 and as a carrier of proteins and free fatty acids in adipocytes.
S-100 (β-Subunit) acts as a marker of melanocyte cytotoxicity. Reduced expression of S100B is observed in chronic liver diseases. It also acts as a serum marker in endocrine resistant breast cancer.
