Abstract Antibodies (Ab) are commonly used in affinity chromatography (AC) as a versatile and specific means of isolating target molecules from complex mixtures. A number of procedures have been developed to immobilize antibodies on the solid matrix. Some of these methods couple the antibody via chemical groups that may be important for specific recognition of antigen, resulting in loss of functionality in a proportion of the antibodies. In other methods, the outcome of immobilization is coupling via unique sites in the Fc region of the antibody molecule, ensuring orientation of the antibody combining sites (Fab) towards the mobile phase. This review discusses the advantages and disadvantages of the various methods available for immobilization and outlines protocols for site-directed, covalent coupling of the antibody to the solid phase that essentially retains the activity of the antibody.
