Application This ELISA kit applies to the in vitro quantitative determination of Rat CTXⅠ 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 Rat CTXⅠ. Standards or samples are added to the micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Rat CTXⅠ 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 Rat CTXⅠ, 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 Rat CTXⅠ. You can calculate the concentration of Rat CTXⅠ in the samples by comparing the OD of the samples to the standard curve.

Technical Data

Precision

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

Recovery

The recovery of Rat CTXⅠ 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) 94-110 102
EDTA plasma (n=8) 92-109 99
Cell culture media (n=8) 92-106 98

Linearity

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