Principle of Assay
Mouse RXRG ELISA Kit (A78755) is a 4 hour sandwich Enzyme-Linked Immunosorbent Assay (sELISA) designed for the in vitro quantitative determination of mouse RXRG in serum, plasma, tissue homogenates, and other biological fluids. A 96-well microtiter plate has been pre-coated with an antibody specific for RXRG. Standards and samples are added to the wells, where RXRG binds to the immobilized capture antibody. Following incubation, unbound components are removed by washing and a biotinylated detection antibody specific for RXRG is added to the wells. The detection antibody binds the captured RXRG 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 RXRG captured in each well. The concentration of RXRG is calculated by reading the absorbance at 450 nm and comparing the values with the standard curve.
