Product Summary
The Quantikine® Human Total IL-18/IL-1F4 Immunoassay is a 4.0 hour solid-phase ELISA designed to measure human IL-18 in cell culture supernates, serum, plasma, saliva, and urine. It contains E. coli-expressed recombinant human IL-18 and has been shown to accurately quantitate the recombinant factor free and in complex with IL-18 BPa. Results obtained using natural human IL-18 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-18.
Precision
Intra-Assay Precision (Precision within an assay) Three samples of known concentration were tested twenty times on one plate to assess intra-assay precision
Inter-Assay Precision (Precision between assays) Three samples of known concentration were tested in twenty separate assays to assess inter-assay precision. Assays were performed by at least three technicians using two lots of components
