Product Details


Assay type Sandwich-ELISA
Format 96T
Assay time 3.5h
Detection range 0.31-20 ng/mL
Sensitivity 0.19 ng/mL
Sample type &Sample volume cell culture supernatant and tissue homogenate; 100μL
Specificity This kit recognizes Rat INS in samples. No significant cross-reactivity or interference between Rat INS 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 Rat INS concentrations in cell culture supernatant and tissue homogenate.

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 INS. 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 INS 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 INS, 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 INS. You can calculate the concentration of Rat INS in the samples by comparing the OD of the samples to the standard curve.

Technical Data


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