Rat S100B (S100 Calcium Binding Protein B) ELISA Kit

The kit is a Sandwich enzyme immunoassay for in vitro quantitative measurement of S100B in serum, plasma and other biological fluids. Detection Range: 62.5--4000pg/mL. Sensitivity: 37.5pg/mL. Protein function: Weakly binds calcium but binds zinc very tightly- distinct binding sites with different affinities exist for both ions on each monomer. Physiological concentrations of potassium ion antagonize the binding of both divalent cations, especially affecting high-affinity calcium-binding sites. Binds to and initiates the activation of STK38 by releasing autoinhibitory intramolecular interactions within the kinase. Interaction with AGER after myocardial infarction may play a role in myocyte apoptosis by activating ERK1/2 and p53/TP53 signaling. Could assist ATAD3A cytoplasmic processing, preventing aggregation and favoring mitochondrial localization. May mediate calcium-dependent regulation on many physiological processes by interacting with other proteins, such as TPR-containing proteins, and modulating their activity. [The UniProt Consortium]
