Application
This ELISA kit applies to the in vitro quantitative determination of Ang-II concentrations in serum, plasma and other biological fluids.
Test Principle
This ELISA kit uses the Competitive-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with Ang-Ⅱ. During the reaction, Ang-Ⅱ in the sample or standard competes with a fixed amount of Ang-Ⅱ on the solid phase supporter for sites on the Biotinylated Detection Ab specific to Ang-Ⅱ. Excess conjugate and unbound sample or standard are washed away, and Avidin-Horseradish Peroxidase (HRP) conjugate are added to each micro plate well and incubated. Then a TMB substrate solution is added to each well. The enzyme-substrate reaction is terminated by the addition of stop solution and the color turns from blue to yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 nm ± 2 nm. The concentration of Ang-Ⅱ in tested samples can be calculated by comparing the OD of the samples to the standard curve.
