However, guided by the information in this article, you can design a first approach to purify your antibody or fragments of interest. Don’t hesitate to go off the beaten track and explore innovative strategies to find new solutions! The purification of antibodies using chromatography involves the separation of antibodies or antibody-derived molecules present in complex mixtures by passing them through a solid phase (eg, silica resin or beads, monolithic columns, or cellulose membranes) and allowing the antibodies to bind or pass through depending on whether "bind-and-elute" or "flow-through" chromatographic methods are employed. Antibody purification can be rather crude (as in precipitation of a fraction containing immunoglobulins and other proteins), particular to immunoglobulins as a group or highly specific to only those antibodies in a sample that bind to a given antigen. Antibodies can be purified by a variety of methods based on their unique physical and chemical properties such as size, solubility, charge, hydrophobicity and binding affinity. This chapter focuses on ammonium sulfate precipitation as a convenient first step in antibody purification in that, it allo … Antibody Purification Basics Polyclonal antibodies, monoclonal antibodies and antibody fragments are usually purified by affinity chromatography from serum, ascites fluid or cell culture medium.
