Product Summary
The Quantikine Human TFF3 Immunoassay is a 4.5 hour solid-phase ELISA designed to measure human TFF3 in cell culture supernates, serum, plasma, saliva, and urine. It contains CHO cell-expressed recombinant human TFF3 and has been shown to accurately quantitate the recombinant factor. Results obtained using natural human TFF3 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 TFF3.
Precision
Intra-Assay Precision (Precision within an assay) Three samples of a known concentration were tested on one plate to assess intra-assay precision
Inter-Assay Precision (Precision between assays) Three samples of a known concentration were tested in separate assays
to determine inter-assay precision. Assays were performed by at least
three technicians using two lots of kit components

Linearity
To assess the linearity of the assay, samples containing high concentrations of human TFF3 were serially diluted with Calibrator Diluent to produce samples with values within the dynamic range of the assay.
