S100 Protein, beta, Recombinant, Human (S100beta, S100B, NEF, Protein S100-B, S-100 Protein beta Chain, S-100 Protein beta Subunit, S100 Calcium-binding Protein B, S100 Calcium Binding Protein beta (Neural), S100 Calcium Binding Protein beta Chain, S100 P

S100 proteins belong to a family of EF-hand calcium binding proteins that exist mostly as dimers of the 20 currently identified individual S100 monomers. The S100B homodimer is expressed in cells of the central nervous system, glial cells and in certain peripheral cells e.g. Schwann cells, melanocytes, adipocytes and chondrocytes. The determination of S100B in serum levels may be used to monitor the extent of brain injury and malignant melanoma.\n\nS100B Human Recombinant produced in E.coli is a single, non-glycoslyated, polypeptide chain containing 91 amino acids fragment (2-92) with an amino-terminal hexahistidine tag, having a total molecular mass of 14.7kD.\n\nStorage and Stability:\nMay be stored at 4 degrees C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20 degrees C. Aliquots are stable for at least 6 months at -20 degrees C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
