Principle of Assay
Human MT1G ELISA Kit (A78470) is a 4 hour sandwich Enzyme-Linked Immunosorbent Assay (sELISA) designed for the in vitro quantitative determination of human MT1G in serum, plasma, tissue homogenates, and other biological fluids. A 96-well microtiter plate has been pre-coated with an antibody specific for MT1G. Standards and samples are added to the wells, where MT1G binds to the immobilized capture antibody. Following incubation, unbound components are removed by washing and a biotinylated detection antibody specific for MT1G is added to the wells. The detection antibody binds the captured MT1G 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 MT1G captured in each well. The concentration of MT1G is calculated by reading the absorbance at 450 nm and comparing the values with the standard curve.
