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.
