Product Summary
The Quantikine Human CHI3L1 Immunoassay is a 4.5 hour solid phase ELISA designed to measure CHI3L1 in cell culture supernates, serum, plasma, and urine. It contains NS0-expressed recombinant human CHI3L1 and antibodies raised against recombinant human CHI3L1 and has been shown to accurately quantitate the recombinant factor. Results obtained using natural CHI3L1 showed dose response 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 CHI3L1.
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 containing high concentrations of CHI3L1 were serially diluted with Calibrator Diluent to produce samples with values within the dynamic range of the assay.
