title: Preparative electrophoresis of isotopically labeled L-cell interferons.
abstract: The preparative method of polyacrylamide gel electrophoresis was adapted for purification and characterization of isotopically labeled L-cell interferons. Re-covery of interferon activity was quantitative, and purification and resolution were comparable to those obtained by analytical polyacrylamide gel electrophoresis. Ultimate specific activities attainable ranged from 2 x 10(6) to 3 x 10(6) international units per mg of protein.
