产品信息

背景说明： S100-B，is an acidic protein with a molecular weight of 21 kDa belonging to the S100 family.S100-B contains two EF-hand-type calcium-binding motifs separated by a hinge region with a hydrophobic cleft.S100-B plays an important role in neurodevelopment，differentiation，and brain construction.S100-B has neuroprotective effects，but at high concentrations S100-B is neurotoxic.Extracellular concentration of S100-B increases following brain damage，which easily penetrates into cerebrospinal fluid in brain damage and then into the blood.S100-B is expressed and produced by astrocytes in vertebrate brains and in the CNS，and the astrocytes are the major cells producing S100-B protein in gray matter，as well as oligodendrocytes are the predominant S100-B in protein producing cells in white matter.The major advantage of using S100-B is that elevations in serum or CSF levels provide a sensitive measure for determining CNS injury at the molecular level before gross changes develop，enabling timely delivery of crucial medical intervention before irreversible damage occurs.In addition，S100-B，which is also present in human melanocytes，is a reliable marker for melanoma malignancy both in bioptic tissue and in serum.
