An improved procedure involving a dual-column gel-filtration system for the separation of ovomucin subunits is described. Ovomucin, prepared from thick egg albumin by precipitation, was separated in the presence of sodium dodecyl sulfate (SDS) and beta-mercaptoethanol by using two Sephacryl S-400 HR gel-filtration columns connected in series. The separation resulted in the isolation of eight peaks. The amino acid compositions and SDS-polyacrylamide gradient gel electrophoretic pattern of each peak were determined.
