“Quanticon” Rat BMP-7(Bone Morphogenetic Protein 7) ELISA Kit

Principle

The test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to BMP-7. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to BMP-7. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain BMP-7, biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of stop solution and the color change is measured spectrophotometrically at a wavelength of 450nm ± 10nm. The concentration of BMP-7 in the samples is then determined by comparing the OD of the samples to the standard curve.

Specification

PRECISION

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

Rate of recovery

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