摘要
Two fast methods for the purification of mouse monoclonal antibodies from ascites fluids using Blue-DEAE and 'thiophilic' absorbent (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 absorbent 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.
