Principle of Assay
Mouse FAH ELISA Kit (A335168) is a 4 hour sandwich Enzyme-Linked Immunosorbent Assay (sELISA) designed for the in vitro quantitative determination of mouse FAH 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 FAH. Standards and samples are added to the wells, where FAH binds to the immobilized capture antibody. Following incubation, unbound components are removed by washing and a biotinylated detection antibody specific for FAH is added to the wells. The detection antibody binds the captured FAH 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 FAH captured in each well. The concentration of FAH is calculated by reading the absorbance at 450 nm and comparing the values with the standard curve.
