S100 proteins are localized in the cytoplasm and nucleus of a wide range of cells, and involved in the regulation of a number of cellular processes such as cell cycle progression and differentiation. S100B is glial-specific and is expressed primarily by astrocytes, but not all astrocytes express S100B. It has been shown that S100B is only expressed by a subtype of mature astrocytes that ensheath blood vessels and by NG2-expressing cells. This protein may function in neurite extension, proliferation of melanoma cells, stimulation of Ca2+ fluxes, inhibition of PKC-mediated phosphorylation, astrocytosis and axonal proliferation, and inhibition of microtubule assembly. In the developing CNS it acts as a neurotrophic factor and neuronal survival protein.
Rat S100 calcium binding protein B (S-100B) ELISA Kit employs a two-site sandwich ELISA to quantitate S-100B in samples. An antibody specific for S-100B has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyS-100B present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for S-100B is added to the wells. After washing, Streptavidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of S-100B bound in the initial step. The color development is stopped and the intensity of the color is measured.
