| Abstract: | Abstract Affinity chromatographic methods for purifying antibodies are reviewed. Topics reviewed include (a) the matrices used in the preparation of the affinity supports; (b) the chemistries commonly used to attach affinity ligands directly on hydroxyl‐carrying supports and indirectly through the use of bifunctional agents to crosslink the affinity ligands to the supports; (c) methods for detecting ligand leakage; (d) macromolecular affinity ligands; (e) low molecular weight peptidyl affinity ligands; (f) low molecular weight non‐peptidyl affinity ligands; (g) optimal conditions for achieving improved product yield; and (h) optimal elution systems that minimize the denaturation of the purified antibodies. |
