Description

The homodimeric S-100 isoform composed of betabeta-subunits, purified from bovine brain. The S-100 proteins are acidic Ca2+ binding proteins found predominately in glial cells. Evidence indicates that upon binding to Ca2+, S-100 proteins expose a hydrophobic domain to the solvent in a manner similar to calmodulin. Within the cell, S-100 proteins have been reported to regulate adenylate cyclase, aldolase activities, ATPase, microtubules, and protein phosphorylation. Under nonreducing conditions both the dimeric and monomeric forms may be visible.Note: This product is not to be used for animal treatment, in vivo research or in any other contact procedure with livestock., Native homodimeric S-100b isoform composed of betabeta-subunits, purified from bovine brain. Elevated serum level of S-100b is used as a marker of stroke and cerebral edema.
