Nori Bovine FGFb ELISA Kit
$461.00 – $832.00
This ELISA kit is for quantification of FGFb in bovine. This is a quick ELISA assay that reduces time to 50% compared to the conventional method, and the entire assay only takes 3 hours. This assay employs the quantitative sandwich enzyme immunoassay technique and uses biotin-streptavidin chemistry to improve the performance of the assays. An antibody specific for FGFb has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and any FGFb present is bound by the immobilized antibody. After washing away any unbound substances, a detection antibody specific for FGFb is added to the wells. Following wash to remove any unbound antibody reagent, a detection reagent is added. After intensive wash a substrate solution is added to the wells and color develops in proportion to the amount of FGFb bound in the initial step. The color development is stopped, and the intensity of the color is measured.
Alternative names for FGFb: Basic fibroblast growth factor, bFGF, FGF2 or FGF-β

Background:
Basic fibroblast growth factor, also known as bFGF, FGF2 or FGF-β, is a member of the fibroblast growth factor family (1). In normal tissue, basic fibroblast growth factor is present in basement membranes and in the subendothelial extracellular matrix of blood vessels. It stays membrane-bound as long as there is no signal peptide. It has been hypothesized that, during both wound healing of normal tissues and tumor development, the action of heparan sulfate-degrading enzymes activates bFGF, thus mediating the formation of new blood vessels, a process known as angiogenesis. bFGF has been shown in preliminary animal studies to protect the heart from injury associated with a heart attack, reducing tissue death and promoting improved function after reperfusion (2). Recent evidence has shown that low levels of FGF2 play a key role in the incidence of excessive anxiety. Basic fibroblast growth factor has been shown to interact with casein kinase 2, alpha 1(3), RPL6 (4) and ribosomal protein S19 (5).
