Principle of Assay
Human ATP6V1D ELISA Kit (A326418) is a 4 hour sandwich Enzyme-Linked Immunosorbent Assay (sELISA) designed for the in vitro quantitative determination of human ATP6V1D in serum, plasma, cell culture supernatant, cell or tissue lysate, and other biological fluids. A 96-well microtiter plate has been pre-coated with an antibody specific for ATP6V1D. Standards and samples are added to the wells, where ATP6V1D binds to the immobilized capture antibody. Following incubation, unbound components are removed by washing and a biotinylated detection antibody specific for ATP6V1D is added to the wells. The detection antibody binds the captured ATP6V1D to form an antibody-antigen-antibody sandwich complex. After further incubation and washing, HRP-Streptavidin conjugate is added to the wells. TMB substrate solution is then 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 yellow colour is directly proportional to the amount of ATP6V1D captured in each well. The concentration of ATP6V1D is calculated by reading the absorbance at 450 nm and comparing the values with the standard curve.
