At first, the labeled antigens will bind to the antibodies hence radioactivity will be maximum. If the sample contains specific antigens of interest, it will bind to the antibodies releasing labeled antigens and hence the radioactivity of the solution will decrease. So by observation of decreasing radioactivity, it can be … Ver más Radiolabeled antigens: The antigens are generally labeled with gamma-ray emitting isotopes such as I-125 and beta-ray emitting isotopes such as Tritium. They are also called hot antigens. Specific Antibodies: They are … Ver más Antigens and antibodies bind specifically to form the Ag-Ab complex.
