Direct ELISA has the advantages of simplicity, convenience, and rapidity, especially suitable for detecting antigens and antibodies in biological samples. In direct ELISA, there is no need to use secondary antibodies, which avoids cross-reactivity and makes the assay results less prone to errors. However, because the antigen of direct ELISA is not specifically fixed, all proteins in the sample (target proteins and other impurity proteins) will bind to the ELISA plate, and the experimental background will be higher.
