WebbIn direct detection methods, the primary antibody is directly conjugated to a label. During indirect detection, the primary antibody is bound by a labeled secondary antibody that has been raised against the host species of the primary antibody. Indirect methods may also include amplification steps to increase signal intensity. Webb14 sep. 2024 · Primary antibodies bind to the antigen detected, whereas secondary antibodies bind to primary antibodies, usually their Fc domain. Secondly, primary antibodies are always needed in immunoassays, whereas secondary antibodies are not necessarily needed, which depends on experimental method (direct or indirect labeling).
