EasyStep Human AngII (Angiotensin II) ELISA Kit

This assay employs the competitive inhibition enzyme immunoassay technique. The microtiter plate provided in this kit has been pre-coated with Human AngII antigen, and the Human AngII standard plate wells that pre-coated using protein-related techniques are provided separately. Standard/Sample Diluent Buffer or samples are added to the appropriate microtiter plate wells ,then added a HRP-conjugated antibody specific to Human AngII to each microplate well and incubated . After TMB substrate solution is added, the enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm ±10nm. The concentration of Human AngII in the samples is then determined by comparing the OD of the samples to the standard curve.Detection Range: 15.63-1000 pg/mL. Sensitivity: 10.63 pg/mL. Assay Type: Competitive Inhibition. Standard: 1000 pg/mL. Sample Type: sSerum, plasma. Assay duration: 1.5h. Protein Function: Essential component of the renin-angiotensin system (RAS), a potent regulator of blood pressure, body fluid and electrolyte homeostasis , Acts directly on vascular smooth muscle as a potent vasoconstrictor, affects cardiac contractility and heart rate through its action on the sympathetic nervous system, and alters renal sodium and water absorption through its ability to stimulate the zona glomerulosa cells of the adrenal cortex to synthesize and secrete aldosterone (PubMed:10619573, PubMed:17138938). Acts by binding to angiotensin receptors AGTR1 and AGTR2 (PubMed:1567413). Also binds the DEAR/FBXW7-AS1 receptor (By similarity) , Stimulates aldosterone release , Is a ligand for the G-protein coupled receptor MAS1 (By similarity). Has vasodilator and antidiuretic effects. Has an antithrombotic effect that involves MAS1-mediated release of nitric oxide from platelets (By similarity) [The Uniprot Consortium]
