Application This ELISA kit applies to the in vitro quantitative determination of Bb 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 Bb. During the reaction, Bb in the sample or standard competes with a fixed amount of Bb on the solid phase supporter for sites on the Biotinylated Detection Ab specific to Bb. 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 Bb in tested samples can be calculated by comparing the OD of the samples to the standard curve.

Kit components & Storage

An unopened kit can be stored at 2-8℃ for 1 month. If the kit is not supposed to be used within 1 month, store the components separately according to the following conditions once the kit is received.

Technical Data

Precision

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

Recovery

The recovery of Bb 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) 87-103 94
EDTA plasma(n=8) 88-102 94
Cell culture media(n=8) 90-107 97

Linearity

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