Application This ELISA kit applies to the in vitro quantitative determination of EPI 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 EPI. During the reaction, EPI in the sample or standard competes with a fixed amount of EPI on the solid phase supporter for sites on the Biotinylated Detection Ab specific to EPI. 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 EPI 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 EPI were tested 20 times on one plate, respectively.
Inter-assay Precision (Precision between assays): 3 samples with low, mid range and high level EPI were tested on 3 different plates, 20 replicates in each plate.

The recovery of EPI 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) 88-101 93
EDTA plasma(n=8) 95-109 101
Cell culture media(n=8) 89-100 95


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