Product Summary
The Quantikine Human S100A8/S100A9 Heterodimer Immunoassay is a 4.5 hour solid-phase ELISA designed to measure human S100A8/S100A9 Heterodimer in cell culture supernates, tissue lysastes, serum, plasma, saliva, urine, human milk, and fecal extract. It contains E. coli-expressed recombinant human S100A8/S100A9 Heterodimer and antibodies raised against the recombinant factor. Results obtained using natural human S100A8/S100A9 Heterodimer 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 naturally occurring human S100A8/S100A9 Heterodimer.
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

Linearity
To assess the linearity of the assay, samples containing and/or spiked with high concentrations of human S100A8/S100A9 Heterodimer were diluted with Calibrator Diluent to produce samples with values within the dynamic range of the assay.
