Product Summary
The Quantikine Human IL-13 Immunoassay is a 4.5 hour solid phase ELISA designed to measure IL-13 levels in cell culture supernates, serum, and plasma. It contains E. coli-expressed recombinant human IL-13 and antibodies raised against the recombinant factor. This immunoassay has been shown to quantitate recombinant human IL-13 accurately. Results obtained using natural human IL-13 showed dose response curves that were parallel to the standard curves obtained using the recombinant kit standards. These results indicate that this kit can be used to determine relative mass values for natural human IL-13.
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 linearity of the assay, samples were spiked with high concentrations of IL-13 and diluted with the appropriate Calibrator Diluent to produce samples with values within the dynamic range of the assay.
