IL1RN ELISA Kit (Rabbit)

Intra-assay Precision (Precision within an assay) : 3 samples with low, middle and high level Interleukin 1 Receptor Antagonist (IL1RA) were tested 20 times on one plate, respectively. Inter-assay Precision (Precision between assays) : 3 samples with low, middle and high level Interleukin 1 Receptor Antagonist (IL1RA) were tested on 3 different plates, 8 replicates in each plate. CV (%) = SD/meanX100 Intra-Assay: CV<10% Inter-Assay: CV<12%

IcIL-1ra; IL1 inhibitor; IL-1ra; IL1RA; IL-1RN; interleukin 1 receptor, type I; interleukin-1 receptor antagonist intracellular form; interleukin-1 receptor antagonist protein; IRAP.

Inhibits the activity of interleukin-1 by binding to receptor IL1R1 and preventing its association with the coreceptor IL1RAP for signaling. Has no interleukin-1 like activity.

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 Interleukin 1 Receptor Antagonist (IL1RA) . Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to Interleukin 1 Receptor Antagonist (IL1RA) . 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 Interleukin 1 Receptor Antagonist (IL1RA), 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 Interleukin 1 Receptor Antagonist (IL1RA) in the samples is then determined by comparing the O.D. of the samples to the standard curve.
