Nori Sheep FGFa ELISA Kit
$508.00 – $916.00
DataSheet Â
This ELISA kit is for quantification of FGFa in sheep. 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 FGFa has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and any FGFa present is bound by the immobilized antibody. After washing away any unbound substances, a detection antibody specific for FGFa 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 FGFa bound in the initial step. The color development is stopped, and the intensity of the color is measured.
Alternative names for FGFa: acidic fibroblast growth factor, FGF-1, ECGF, HBGF1

Background:Â
Acidic fibroblast growth factor known as FGF acidic, also known as FGF-1, ECGF, and HBGF-1, is a mitogenic peptide that is produced by multiple cell types and stimulates the proliferation of cells of mesodermal, ectodermal, and endodermal origin. FGF acidic is involved in wound repair, angiogenesis, and development. FGF acidic is secreted from cells via an endoplasmic reticulum/Golgi independent mechanism (1, 2). The ability of FGF acidic to bind to heparin sulfate is required for its ability to interact with FGF receptors and induce signaling (1-4). There are four distinct FGF receptors and each has multiple splice variants. FGF acidic binds with high affinity to many, but not all, FGFRs. Signaling cascades activated through FGF basic binding to FGFR include the ras-raf-MAPK, PLCγ/PKC, and PI3K/Akt pathways.
