• Antibody Target Identification
Antibody target identification is the process of determining biomolecules (targets) that an antibody specifically recognizes and binds. This process relies on the principle of antigen-antibody specificity. For instance, immunoprecipitation involves forming antibody-antigen complexes in solution, which are then precipitated using substances that bind to the Fc region of the antibody, allowing target analysis. In affinity chromatography, antibodies are immobilized on a chromatographic medium, and sample......
