Sample type &Sample volume serum, plasma and other biological fluids; 100μL
Specificity This kit recognizes Rat IL-4 in samples. No significant cross-reactivity or interference between Rat IL-4 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 IL-4 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 IL-4. 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 IL-4 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 IL-4, 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 IL-4. You can calculate the concentration of Rat IL-4 in the samples by comparing the OD of the samples to the standard curve.

Recovery

The recovery of Rat IL-4 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) 91-102 97
EDTA plasma (n=8) 86-99 93
Cell culture media (n=8) 91-103 96

Linearity

Samples were spiked with high concentrations of Rat IL-4 and diluted with Reference Standard & Sample Diluent to produce samples with values within the range of the assay.
