“Quanticon” Mouse Interleukin 2, IL-2 ELISA KIT

Principle

This kit uses the Sandwich-ELISA principle. The microtiter plate strips has been pre-coated with an affinity purified antibody to Mouse IL-2. Standards or samples containing Mouse IL-2 are added to the plate and reacted with capture antibody. A second anti-Mouse IL-2 antibody labeled biotin is then added and binds to Mouse IL-2 captured on the plate. After that, Streptavidin-Horseradish Peroxidase(SA-HRP) is added to form a sandwich complex of solid phase antibody-Mouse IL-2-biotin labeled antibody-SA-HRP. And then, TMB substrate solution is added to all wells and incubated. An enzyme-catalyzed reaction generates a blue color in the solution, thereafter, stop solution is added to stop the substrate reaction and the color turns yellow. The yellow solution is read at a wavelength of 450nm. The concentration of Mouse IL-2 in the samples is then calculated from the OD value by establishing a standard curve.

Specification

Precision

Mean coefficient of variation for Intra-Assay and Inter-Assay: 3 samples with low, middle and high level concentration were tested for repeat multiple times, respectively.

Rate of recovery

Three matrices listed below were spiked with certain level of Mouse IL-2, The recovery rates of Mouse IL-2 were calculated by comparing the measured value to the expected amount of Mouse IL-2 in samples.
