For In Vitro Research Use Only-Not for Use in or on human or animals-not for use in diagnostics

Background: S-100 protein derived from brain tissue is an acidic calcium-binding protein with molecular weight of about 21kda. In human brain tissue, S-100 protein is mainly presented by two isoforms, a Beta-Beta(BB) homodimer or S-100b and an Alpha-Beta (AB) heterodimer or S-100a. Becasue of its predomiant location in astrological cells, S-100 protein can be used as a sensitive and reliable marker for central nervous system injury. Structural damage of glial cells causes leakage of S-100 protein into extracellular matrix and into cerebrospinal fluid, further releasing into the bloodstream. Measurements of S-100 protein in patient serum samples may eb useful in monitoring of traumatic brain injury, ischemic brain damage after circulatory arrests, in    diagnosis and prognosis of clinical outcome in acute stroke.

Warning: Prepared from human tissue; As no method can assure complete non-infectivity, material should be handled under Biosafety Level II (CDC) condition and treated as if capable of transmitting infection.
