Principiul testului

Universal Total 25-OH Vitamin D ELISA Kit (A335461) is a 2 hour competitive Enzyme-Linked Immunosorbent Assay (cELISA) designed for the in vitro quantitative determination of universal Total 25-OH Vitamin D in serum, plasma, cell culture supernatant, cell or tissue lysate, and other biological fluids. A 96-well microtiter plate has been pre-coated with Total 25-OH Vitamin D. During the assay, Total 25-OH Vitamin D present in the standards or samples competes with immobilized Total 25-OH Vitamin D for binding to an assay-specific antibody. Following incubation, unbound components are removed by washing and HRP-Streptavidin conjugate is added to the wells. After further incubation and washing, TMB substrate solution is added to visualize the HRP enzymatic reaction. This produces a blue-coloured product that changes to yellow following addition of acidic stop solution. The intensity of the colour is measured at 450 nm using a microplate reader. The concentration of Total 25-OH Vitamin D in the samples is inversely proportional to the OD450 value and is determined by comparison with the standard curve.
