Anti-Target Affinity Gel is a general term used to describe any chromatographic resin that contains immobilized antibodies designed to specifically recognize and bind to a particular target protein. The "target" in this context can refer to a wide range of proteins, depending on the specific application and research interest. How Anti-Target Affinity Gel Works: Protein binding: The target protein binds specifically to the immobilized antibodies on the gel. Washing: Unbound proteins are washed away. Elution: The bound target protein is eluted from the gel using a competitive elution buffer or by changing the pH or ionic strength of the buffer.
