Principle of Assay
Mouse MT4-MMP ELISA Kit (A74892) is a 4 hour sandwich Enzyme-Linked Immunosorbent Assay (sELISA) designed for the in vitro quantitative determination of mouse MT4-MMP in serum, plasma, tissue homogenates, and other biological fluids. A 96-well microtiter plate has been pre-coated with an antibody specific for MT4-MMP. Standards and samples are added to the wells, where MT4-MMP binds to the immobilized capture antibody. Following incubation, unbound components are removed by washing and a biotinylated detection antibody specific for MT4-MMP is added to the wells. The detection antibody binds the captured MT4-MMP 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 MT4-MMP captured in each well. The concentration of MT4-MMP is calculated by reading the absorbance at 450 nm and comparing the values with the standard curve.
