Interleukin 1 Receptor Antagonist, IL-1ra BioAssay™ ELISA Kit (Mouse)

For the quantitative determination of mouse Interleukin 1 receptor antagonist concentrations in serum, plasma, and tissue homogenates.

Sensitivity:
15.6pg/ml

Detection Range:
62.5-4000pg/ml

Specificity:
This assay has high sensitivity and excellent specificity for detection of mouse IL-1ra. No significant cross-reactivity or interference between mouse IL-1ra and analogues was observed.

Assay Principle:
This assay employs the quantitative sandwich enzyme immunoassay technique. Antibody specific for IL-1ra has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and any IL-1ra present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for IL-1ra is added to the wells. After washing, avidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of IL-1ra bound in the initial step. The color development is stopped and the intensity of the color is measured.
