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 Toll Like Receptor 2 (TLR2). Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to Toll Like Receptor 2 (TLR2). 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 Toll Like Receptor 2 (TLR2), biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm +/- 10nm. The concentration of Toll Like Receptor 2 (TLR2) in the samples is then determined by comparing the O.D. of the samples to the standard curve.
ELISA Kit Range
0.312-20ng/mL
ELISA Kit Reproducibility
Intra-assay Precision (Precision within an assay): 3 samples with low, middle and high level Toll Like Receptor 2 (TLR2) were tested 20 times on one plate, respectively. Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level Toll Like Receptor 2 (TLR2) were tested on 3 different plates, 8 replicates in each plate. CV(%) = SD/meanX100 Intra-Assay: CV<10% Inter-Assay: CV<12%
