WebIn an ELISA assay, the antigen is immobilized to a solid surface. This is done either directly or via the use of a capture antibody itself immobilized on the surface. The antigen is then … WebELISA assays are usually chromogenic using a reaction that converts the substrate (e.g. TMB or ABTS) into a coloured product which can be measured using a plate reader. Determination of antigen concentration in a sample requires production of a standard curve using antigens of a known concentration (shown in Figure 2 ).
