Product Summary for Human TFF3 Quantikine ELISA Kit
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.

Recovery for Human TFF3 Quantikine ELISA Kit
The recovery of human TFF3 spiked to levels throughout the range of the assay was evaluated.
| Sample Type | Average % Recovery | Range % |
|---|---|---|
| Cell Culture Supernates (n=4) | 100 | 90-114 |
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.
