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.

Technical Data


Intra-assay Precision (Precision within an assay): 3 samples with low, mid range and high level Ang-Ⅱ were tested 20 times on one plate, respectively.
Inter-assay Precision (Precision between assays): 3 samples with low, mid range and high level Ang-Ⅱ were tested on 3 different plates, 20 replicates in each plate.

The recovery of Ang-Ⅱ spiked at three different levels in samples throughout the range of the assay was evaluated in various matrices.

Sample Type Range (%) Average Recovery (%)
Serum(n=8) 88-100 94
EDTA plasma(n=8) 90-104 96
Cell culture media(n=8) 84-96 91


Samples were spiked with high concentrations of Rat Ang-Ⅱ and diluted with Reference Standard & Sample Diluent to produce samples with values within the range of the assay.
