Human

This assay has high sensitivity and excellent specificity for detection of S100B. No significant cross-reactivity or interference between S100B and analogues was observed. NOTE: Limited by current skills and knowledge, it is impossible for us to complete the cross-reactivity detection between S100B and all the analogues, therefore, cross reaction may still exist in some cases.

Store all reagents at 2-8 degree C.

Typical Testing Data/Standard Curve (for reference only)

Samples: Serum, Plasma, Cell Culture Supernatants, Body Fluid And Tissue Homogenate. Assay Type: Quantitative Competitive. Sensitivity: 1.0 pg/mL.

Intended Uses: This S100B ELISA kit is a 1.5 hour solid-phase ELISA designed for the quantitative determination of Chicken S100B. This ELISA kit for research use only, not for therapeutic or diagnostic applications!. Principle of the Assay: S100B ELISA kit applies the competitive enzyme immunoassay technique utilizing an anti-S100B antibody and an S100B-HRP conjugate. The assay sample and buffer are incubated together with S100B-HRP conjugate in pre-coated plate for one hour. After the incubation period, the wells are decanted and washed five times. The wells are then incubated with a substrate for HRP enzyme. The product of the enzyme-substrate reaction forms a blue colored complex. Finally, a stop solution is added to stop the reaction, which will then turn the solution yellow. The intensity of color is measured spectrophotometrically at 450nm in a microplate reader. The intensity of the color is inversely proportional to the S100B concentration since S100B from samples and S100B-HRP conjugate compete for the anti-S100B antibody binding site. Since the number of sites is limited, as more sites are occupied by S100B from the sample, fewer sites are left to bind S100B-HRP conjugate. A standard curve is plotted relating the intensity of the color (O.D.) to the concentration of standards. The S100B concentration in each sample is interpolated from this standard curve.

The protein encoded by this gene is a member of the S100 family of proteins containing 2 EF-hand calcium-binding motifs. S100 proteins are localized in the cytoplasm and/or 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. S100 genes include at least 13 members which are located as a cluster on chromosome 1q21; however, this gene is located at 21q22.3. 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. Chromosomal rearrangements and altered expression of this gene have been implicated in several neurological, neoplastic, and other types of diseases, including Alzheimer's disease, Down's syndrome, epilepsy, amyotrophic lateral sclerosis, melanoma, and type I diabetes.

S100B: 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. Dimer of either two alpha chains, or two beta chains, or one alpha and one beta chain. The S100B dimer binds two molecules of STK38. Interacts with AGER. The S100B dimer interacts with two molecules of CAPZA1. Although predominant among the water-soluble brain proteins, S100 is also found in a variety of other tissues. Belongs to the S-101 family. Protein type: Calcium-binding. Chromosomal Location of Human Ortholog: 21q22.3. Cellular Component: ruffle; extracellular space; intracellular membrane-bound organelle; cell soma; perinuclear region of cytoplasm; cytoplasm; extracellular region; nucleus. Molecular Function: identical protein binding; RAGE receptor binding; protein binding; protein homodimerization activity; zinc ion binding; calcium ion binding; calcium-dependent protein binding; tau protein binding. Biological Process: central nervous system development; positive regulation of I-kappaB kinase/NF-kappaB cascade; positive regulation of apoptosis; response to glucocorticoid stimulus; memory; cell proliferation; regulation of cell shape; learning and/or memory; axonogenesis; astrocyte differentiation; positive regulation of cell proliferation; response to methylmercury; innate immune response; regulation of neuronal synaptic plasticity
