Product Summary
The Quantikine Human IL-1ra Immunoassay is a 4.5 hour solid phase ELISA designed to measure IL-1ra in cell culture supernates, serum, and plasma. It contains E. coli-derived recombinant human IL-1ra as well as antibodies raised against the recombinant factor. This immunoassay has been shown to accurately quantitate recombinant human IL-1ra. Results obtained using natural human IL-1ra showed linear curves that were parallel to the standard curves obtained using the Quantikine kit standards. These results indicate that this kit can be used to determine relative mass values for natural human IL-1ra.
Precision
Intra-Assay Precision (Precision within an assay) Three samples of known concentration were tested on one plate to assess intra-assay precision
Inter-Assay Precision (Precision between assays) Three samples of known concentration were tested in separate assays to assess inter-assay precision

Linearity
To assess the linearity of the assay, samples containing high concentrations of IL-1ra were serially diluted with the appropriate Calibrator Diluent to produce samples with values within the dynamic range of the assay.
