Certain diagnostic, analytical and preparative applications require the separation of immunoglobulin G (IgG) from immunoglobulin M (IgM). In the present work, different ion-exchange methacrylate monoliths were tested for the separation of IgG and IgM. The strong anion-exchange column had the highest dynamic binding capacity reaching more than 20 mg of IgM/ml of support. Additionally, separation of IgM from human serum albumin, a common contaminant in immunoglobulin purification, was achieved on the weak ethylenediamino anion-exchange column, which set the basis for the IgM purification method developed on convective interaction media (CIM) supports. Experiments also confirmed flow independent characteristics of the short monolithic columns.
