Principle of the assay: BLNK ELISA kit applies the competitive enzyme immunoassay technique utilizing a monoclonal anti-BLNK antibody and an BLNK-HRP conjugate. The assay sample and buffer are incubated together with BLNK-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 BLNK concentration since BLNK from samples and BLNK-HRP conjugate compete for the anti-BLNK antibody binding site. Since the number of sites is limited, as more sites are occupied by BLNK from the sample, fewer sites are left to bind BLNK-HRP conjugate. A standard curve is plotted relating the intensity of the color (O.D.) to the concentration of standards. The BLNK concentration in each sample is interpolated from this standard curve.

NCBI Description

This gene encodes a cytoplasmic linker or adaptor protein that plays a critical role in B cell development. This protein bridges B cell receptor-associated kinase activation with downstream signaling pathways, thereby affecting various biological functions. The phosphorylation of five tyrosine residues is necessary for this protein to nucleate distinct signaling effectors following B cell receptor activation. Mutations in this gene cause hypoglobulinemia and absent B cells, a disease in which the pro- to pre-B-cell transition is developmentally blocked. Deficiency in this protein has also been shown in some cases of pre-B acute lymphoblastic leukemia. Alternatively spliced transcript variants have been found for this gene.

Uniprot Description

BLNK: an adaptor protein that bridges the B-cell receptor-associated kinases (BCR) with a multitude of signaling pathways, regulating biologic outcomes of B-cell function and development. Plays an important role in BCR-mediated PLCG1 activation and Ca(2 ) mobilization. Does not seem to be not required for pre-BCR-mediated activation of MAP kinase and phosphatidyl-inositol 3 (PI3) kinase signaling. Plays a critical role in orchestrating the pro-B cell to pre-B cell transition. Following BCR activation, phosphorylated on tyrosine residues by SYK and LYN. When phosphorylated, serves as a scaffold to assemble downstream targets of antigen activation, including PLCG1, VAV1, GRB2 and NCK1. Its phosphorylation is required for both Ca(2 ) and MAPK signaling pathways. Defects in BLNK are the cause of hypoglobulinemia and absent B-cells.It has tumor supressor activity that is lost in many cases of childhood pre-B acute lymphoblastic leukemia (ALL). Two alternatively spliced isoforms have been described; these are differentially involved in activation and apoptosis of B lymphocytes.
