How are direct and indirect elisa different

Web24 de ago. de 2024 · The indirect ELISA is used for similar experiments as the direct ELISA, the only difference being the additional amplification step, which helps to visualize low-abundance proteins. Figure 4: Overview of using Indirect ELISA to quantitatively measure protein concentration or antibody specificity via a colorimetric reaction. WebBased on different methods of capture and detection, ELISA can be of four types: direct, indirect, sandwich, and competitive. For direct ELISA, the target antigen is first bound to the plate, and is then detected by a specific detection antibody. This method is commonly used for screening antibodies for a specific antigen.
