What Is a Secondary Antibody?
A secondary antibody is a special kind of antibody used in experiments to help detect or measure specific proteins or other molecules. It works by attaching to a primary antibody, which is already bound to the target (called the analyte).
Secondary antibodies are used in many types of scientific tests and are available in lots of different forms. One big benefit of using them is that they can amplify the signal, which helps scientists see or measure small amounts of the target more easily.
If you're planning an experiment or setting up an assay, it's easy to buy secondary antibodies that match your specific needs—whether you need enzyme-linked, fluorescent, or biotin-labeled options.
