Immunoaffinity chromatography.
This technique involves elution of a single protein from an immunoaffinity column after prior elution of nonspecifically adsorbed proteins. Antibodies are coupled to Sepharose and the cell lysate is passed over the column. After washing, the specific antigen is eluted from the column using one of a number of methods: brief exposure to either high or low pH, or using the detergent octyl beta-D-glucoside (easily removable by dialysis). All these methods are described in this unit along with a procedure for covalently linking an antibody to Sepharose using the cyanogen bromide activation method.
