FGF23 ELISA Kit (Human)

Intra-assay Precision (Precision within an assay) : 3 samples with low, middle and high level Fibroblast Growth Factor 23 (FGF23) were tested 20 times on one plate, respectively. Inter-assay Precision (Precision between assays) : 3 samples with low, middle and high level Fibroblast Growth Factor 23 (FGF23) were tested on 3 different plates, 8 replicates in each plate. CV (%) = SD/meanX100 Intra-Assay: CV<10% Inter-Assay: CV<12%

ADHR; FGFN; fibroblast growth factor 23; HFTC2; HPDR2; HYPF; phosphatonin; PHPTC; tumor-derived hypophosphatemia inducing factor; Tumor-derived hypophosphatemia-inducing factor.

Regulator of phosphate homeostasis. Inhibits renal tubular phosphate transport by reducing SLC34A1 levels. Upregulates EGR1 expression in the presence of KL (By similarity) . Acts directly on the parathyroid to decrease PTH secretion (By similarity) . Regulator of vitamin-D metabolism. Negatively regulates osteoblast differentiation and matrix mineralization.

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 Fibroblast Growth Factor 23 (FGF23) . Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to Fibroblast Growth Factor 23 (FGF23) . 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 Fibroblast Growth Factor 23 (FGF23), 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 Fibroblast Growth Factor 23 (FGF23) in the samples is then determined by comparing the O.D. of the samples to the standard curve.
