Product Summary
The Quantikine Human sICAM-1 immunoassay is a 2.0 hour solid phase ELISA designed to measure sICAM-1 in cell culture supernates, serum, and plasma. It contains NS0-expressed recombinant human sICAM-1 and has been shown to accurately quantitate the recombinant factor. Results obtained using natural human sICAM-1 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 sICAM-1.
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 spiked with or containing high concentrations of sICAM-1 were serially diluted with Calibrator Diluent to produce samples with values within the dynamic range of the assay.
