Nori Sheep Angiopoietin 1 ELISA Kit
$461.00 – $832.00
This ELISA kit is for quantification of ANG-1 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 ANG-1 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and any ANG-1 present is bound by the immobilized antibody. After washing away any unbound substances, a detection antibody specific for ANG-1 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 ANG-1 bound in the initial step. The color development is stopped, and the intensity of the color is measured.

Background:
Angiopoietin 1 (ANG-1) is a type of angiopoietin and is encoded by the gene ANGPT1. [1] Angiopoietins are proteins with important roles in vascular development and angiogenesis. All angiopoietins bind with similar affinity to an endothelial cell-specific tyrosine-protein kinase receptor.[2] The protein encoded by this gene is a secreted glycoprotein that activates the receptor by inducing its tyrosine phosphorylation. It plays a critical role in mediating reciprocal interactions between the endothelium and surrounding matrix and mesenchyme. The protein also contributes to blood vessel maturation and stability, and may be involved in early development of the heart.[1] Angiopoietin 1 has been shown to interact with TEK tyrosine kinase.
