An Introduction to Primary Antibodies and Secondary Antibodies

WebbThere are two classes of immunofluorescence techniques, primary (or direct) and secondary (or indirect). Primary (direct) Primary, or direct, immunofluorescence uses a single antibody that is chemically linked to a fluorophore. The antibody recognizes the target molecule and binds to it, and the fluorophore it carries can be detected via ... 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).
