FPLC purification of mouse monoclonal antibodies from ascitic fluid using blue DEAE and thiophilic sorbents
1Institute of General and Molecular Pathology, Tartu University, Estonia, U.S.S.R.
Two fast methods for the purification of mouse monoclonal antibodies from ascites, fluids using Blue-DEAE and 'thiophilic' adsorbent (T gel) in the FPLC system are described. Blue-DEAE chromatography is useful only for IgG1, IgG2a and IgG2b monoclonal antibody purification. T gel is a satisfactory adsorbent for IgG2b purification. Other IgG subclasses and IgM can also be obtained by simple one-step procedures, but the preparations contain small amount of high molecular weight contaminants.
