FGF-23, a phosphate-regulating hormone, plays a critical role in phosphorus homeostasis. The study of FGF-23 is important in understanding the role it plays in such processes as bone remodeling and kidney function. FGF-23 is responsible for the inhibition of renal tubular reabsorption of inorganic phosphorus and, consequently, the regulation of phosphorus homeostasis. FGF-23 mRNA is expressed in the brain, in the thymus at low levels, in dendritic cells, with the highest expression in osteocytes and osteoblasts during phases of active bone remodeling. Because circulating levels of FGF-23 are regulated by vitamin D and phosphorus, normal skeletal and soft tissue development require vitamin D and a functional vitamin D signaling pathway. Diseases resulting from aberrant FGF-23 expression include inherited forms of rickets, certain kidney diseases and phosphorus-related tumorsIntended Use: FGF-23, Rat, BioAssay ELISA Kit is used for the non-radioactive quantification of FGF-23 in rat serum, plasma, and tissue culture samples. This kit specifically measures native rat FGF-23. One kit is sufficient to measure 41 unknown samples in duplicate. This kit is for research use only.Detection Range:0.82-20ng/mlSensitivity:0.05ng/mlPrecision:Intra-Assay %CV: <10Inter-Assay %CV: <10Specificity:The antibody pair used in this assay is specific to rat FGF-23 and does not significantly crossreact to the following molecules/hormones tested: other FGFsPrinciple of the Test:This assay is a Sandwich ELISA based, sequentially, on: 1) concurrent capture of rat FGF-23 molecules from samples to the wells of a microtiter plate coated with a polyclonal rabbit anti-FGF-23 antibody, and binding of a second biotinylated polyclonal goat anti-FGF-23 antibody to the captured molecules, 2) washing of unbound materials from samples, 3) binding of streptavidin-horseradish peroxidase conjugate to the immobilized biotinylated antibodies, 4) washing of excess of free enzyme conjugates, and 5) quantification of immobilized antibody-enzyme conjugates by monitoring horseradish peroxidase activities in the presence of the substrate 3,3’,5,5’-tetramethylbenzidine. The enzyme activity is measured spectrophotometrically by the increased absorbance at 450–590nm after acidification of formed products. Since the increase in absorbance is directly proportional to the amount of captured rat FGF-23 in the unknown sample, the latter can be derived by interpolation from a reference curve generated in the same assay with reference standards of known concentrations of rat FGF-23.Kit Components:029475A: FGF-23 ELISA Microtiter Strips, 1x96 wells029475B: HRP Wash Buffer Concentrate, 10X, 2x50ml029475C: FGF-23 Standard, 1x1 vial029475D: FGF-23 Quality Control 1, 0.22-0.46ng/ml, 1x1 vial029475E: FGF-23 Quality Control 2, 1.9-4.0ng/ml, 1x1 vial029475F: Matrix Solution, 1x1.5ml029475G: Assay Buffer, 1x12ml029475H: FGF-23 Detection Antibody, 1x12ml029475J: Streptavidin (HRP), 1x12ml029475K: TMB Substrate, 1x12ml029475L: Stop Solution, 1x12mlStorage and Stability:Recommended storage for kit components is 4°C.
