Application This ELISA kit applies to the in vitro quantitative determination of Rat ACE concentrations in serum, plasma and other biological fluids.

Test Principle

This ELISA kit uses the Sandwich-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with an antibody specific to Rat ACE. Standards or samples are added to the micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Rat ACE and Avidin-Horseradish Peroxidase (HRP) conjugate are added successively to each micro plate well and incubated. Free components are washed away. The substrate solution is added to each well. Only those wells that contain Rat ACE, biotinylated detection antibody and Avidin-HRP conjugate will appear blue in color. The enzyme-substrate reaction is terminated by the addition of stop solution and the color turns yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 nm ± 2 nm. The OD value is proportional to the concentration of Rat ACE. You can calculate the concentration of Rat ACE in the samples by comparing the OD of the samples to the standard curve.

The recovery of Rat ACE 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) 93-107 101
EDTA plasma (n=8) 95-111 102
Cell culture media (n=8) 87-103 94


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