Vitamin D Binding Protein (DBP) BioAssay™ ELISA Kit (Equine)

The Vitamin D Binding Protein (DBP) BioAssay™ ELISA Kit is a sandwich enzyme immunoassay for in vitro quantitative measurement of equine DBP in serum, plasma and other biological fluids.||Sensitivity:|2.84ng/ml||Range:|6.25-400ng/ml||Specificity:|This assay has high sensitivity and excellent specificity for detection of Vitamin D Binding Protein (DBP). No significant cross-reactivity or interference between Vitamin D Binding Protein (DBP) and analogues was observed.||Precision:|Intra-Assay: CV<10% |Inter-Assay: CV<12%||Test Principle:|The microplate provided in this kit has been pre-coated with an antibody specific to DBP. Standards or samples are then added to the appropriate microplate wells with a biotin-conjugated antibody specific to DBP. 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 DBP, 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 DBP in the samples is then determined by comparing the O.D. of the samples to the standard curve.||Kit Components:|96-well strip plate, 1x Plate |Standard, 2x vial|Detection Reagent A, 1×120ul|Detection Reagent B, 1×120ul|TMB Substrate, 1×9ml|Wash Buffer (30X), 1×20ml|Standard Diluent, 1×20ml|Assay Diluent A, 1×12ml|Assay Diluent B, 1×12ml|Stop Solution, 1x6ml||Storage and Stability:|Store all components at 4°C.
