The Quantikine HS Human IL-7 Immunoassay is a solid phase ELISA that specifically measures IL-7 in 18-24 hours (with an overnight incubation step). This kit is designed to measure IL-7 levels in cell culture supernates, serum, and plasma. It contains E. coli-expressed recombinant human IL-7 and antibodies raised against the recombinant factor. It has been shown to quantitate the recombinant factor accurately. Results obtained using natural IL-7 showed linear curves that were parallel to the standard curves obtained using the kit standards. These results indicate that this kit can be used to determine relative mass values for natural human IL-7.

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

The recovery of IL-7 spiked to three different levels throughout the range of the assay was evaluated.

To assess the linearity of the assay, samples were spiked with high concentrations of IL-7 and diluted with the appropriate Calibrator Diluent to produce samples with values within the dynamic range of the assay.
