Nori Sheep TGFb3 ELISA Kit
$461.00 – $832.00
This ELISA kit is for quantification of TGFb3 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 TGFb3 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and any TGFb3 present is bound by the immobilized antibody. After washing away any unbound substances, a detection antibody specific for TGFb3 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 TGFb3 bound in the initial step. The color development is stopped, and the intensity of the color is measured.

Background:Â
Transforming growth factor, beta 3 (TGF-b3) belongs to a large family of cytokines called the Transforming growth factor beta super family (1, 2), which includes the TGF-β family, bone morphogenetic proteins (BMPs), growth and differentiation factors (GDFs), inhibins and activins. TGF-β3 is expressed in numerous cells including epithelial cells (3). TGF-β3 is a Ser/Thr protein kinase and is believed to regulate molecules involved in cellular adhesion and extracellular matrix (ECM) formation during the process of palate development. Without TGF-β3, mammals develop a deformity known as a cleft palate (4). This is caused by failure of epithelial cells in both sides of the developing palate to fuse. TGF-b3 is involved in embryogenesis and cell differentiation. TGF-b3 signaling activates transcription of the LEF1 gene to induce epithelial mesenchymal transformation during mouse palate development (5). TGF-b3 functions in normal palate and lung morphogenesis and is implicated in epithelial-mesenchymal interaction (4). Together with other members of TGF-b, TGF-β3 functions via endoglin, an accessory protein that interacts with the receptors of the TGF-β family (6); TGF-b3 has interaction with the type I receptor ALK-1 (7).
