The antibody is bound to an inert polymer support ,then exposed to reacts with the antigen at a different epitope is added. The second antibody used is one that has an enzyme attached to it that coverts a colorless or nonfluorescent substrate into a colored or fluorescent product. The amount of second antibody bound, and hence the amount of protein antigen present in the original sample, is determined by quantification of the intensity of color or fluorescence produced.
