Principle of Assay
Mouse MIP 1 gamma ELISA Kit (A303416) is a 4 hour sandwich Enzyme-Linked Immunosorbent Assay (sELISA) designed for the in vitro quantitative determination of mouse MIP 1 gamma in serum, plasma, tissue homogenates, and other biological fluids. A 96-well microtiter plate has been pre-coated with an antibody specific for MIP 1 gamma. Standards and samples are added to the wells, where MIP 1 gamma binds to the immobilized capture antibody. Following incubation, unbound components are removed by washing and a biotinylated detection antibody specific for MIP 1 gamma is added to the wells. The detection antibody binds the captured MIP 1 gamma 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 MIP 1 gamma captured in each well. The concentration of MIP 1 gamma is calculated by reading the absorbance at 450 nm and comparing the values with the standard curve.
