Specificity This kit recognizes β-CTx in samples. No significant cross-reactivity or interference between β-CTx and analogues was observed.
Reproducibility Both intra-CV and inter-CV are < 10%.
Application This ELISA kit applies to the in vitro quantitative determination of β-CTx 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 β-CTx. During the reaction, β-CTx in the sample or standard competes with a fixed amount of β-CTx on the solid phase supporter for sites on the Biotinylated Detection Ab specific to β-CTx. 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 β-CTx 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 β-CTx were tested 20 times on one plate, respectively.
Inter-assay Precision (Precision between assays): 3 samples with low, mid range and high level β-CTx were tested on 3 different plates, 20 replicates in each plate.

Recovery

The recovery of β-CTx 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) 88-103 94
EDTA plasma(n=8) 91-104 98
Cell culture media(n=8) 85-96 91

Linearity

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