Application This ELISA kit applies to the in vitro quantitative determination of Human OC/BGP 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 Human OC/BGP. Standards or samples are added to the micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Human OC/BGP 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 Human OC/BGP, 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 Human OC/BGP. You can calculate the concentration of Human OC/BGP in the samples 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 Human OC/BGP were tested 20 times on one plate, respectively.
Inter-assay Precision (Precision between assays): 3 samples with low, mid range and high level Human OC/BGP were tested on 3 different plates, 20 replicates in each plate.

The recovery of Human OC/BGP 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) 92-109 99
EDTA plasma (n=8) 93-109 99
Cell culture media (n=8) 85-97 90


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