TFF1 ELISA Kit (Human)

Intra-assay Precision (Precision within an assay) : 3 samples with low, middle and high level Trefoil Factor 1 (TFF1) were tested 20 times on one plate, respectively. Inter-assay Precision (Precision between assays) : 3 samples with low, middle and high level Trefoil Factor 1 (TFF1) were tested on 3 different plates, 8 replicates in each plate. CV (%) = SD/meanX100 Intra-Assay: CV<10% Inter-Assay: CV<12%

BCEI; breast cancer estrogen-inducible protein; breast cancer estrogen-inducible sequence; D21S21; gastrointestinal trefoil protein pS2; HP1.A; HPS2; pNR-2; polypeptide P1.A; protein pS2; pS2; trefoil factor 1.

Stabilizer of the mucous gel overlying the gastrointestinal mucosa that provides a physical barrier against various noxious agents. May inhibit the growth of calcium oxalate crystals in urine.

The test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Trefoil Factor 1 (TFF1) . Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to Trefoil Factor 1 (TFF1) . Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain Trefoil Factor 1 (TFF1), biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm +/- 10nm. The concentration of Trefoil Factor 1 (TFF1) in the samples is then determined by comparing the O.D. of the samples to the standard curve.
