title: Size-exclusion high-performance liquid chromatography in analysis of protein and peptide epitopes.
abstract: Size-exclusion HPLC provides direct observation of antibody-antigen interactions in free solution without chemical modification of either component. HPLC data collection systems are now a routine resource in both academic and industrial research laboratories. Monoclonal antibodies are, in principle, homogeneous reagents whose interactions with epitope are suitable for unambiguous quantitative characterization. HPLC-based methods, therefore, have the potential to contribute significantly to efficient quantitative characterization of monoclonal antibodies in studies directed to the fundamental physiological roles of these molecules as well as to the optimized selection and quality control of these reagents in biotechnical applications such as represented by the immunodiagnostic industry. In many cases, HPLC-based methods may represent the simplest and most rapid approach for evaluation of relative epitope specificities and affinity/kinetic characteristics of interaction.
