Abstract:
Most immunochemical techniques used in molecular biology rely on a specific class of antibodies, immunoglobulin G (IgG). In mammals, IgG antibodies are produced during the secondary humoral response and contribute about 80% of the serum immunoglobulin. Factors affecting the experimental production of antibodies have been discussed in detail (1). In this chapter we describe a method for the rapid and efficient purification of IgG to near homogeneity from rabbit serum. This is achieved by affinity chromatography using protein A.
