Product Summary
The Quantikine Human Galectin-9 Immunoassay is a 4.5 hour solid-phase ELISA designed to measure human Galectin-9 in cell culture supernates, serum, plasma, saliva, urine, and human milk. It contains E. coli-expressed recombinant human Galectin-9 and has been shown to accurately quantitate the recombinant factor. Results obtained using natural human Galectin-9 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 Galectin-9.
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
Cell Culture Supernates, Saliva, Human Milk

Linearity
To assess the linearity of the assay, samples containing high concentrations of human Galectin-9 were diluted with Calibrator Diluent to produce samples with values within the dynamic range of the assay.
