based on exact two-dimensional comigration with lamin b , both from rat liver lamin and cho nuclear matrix-intermediate filament preparations , and its immunoprecipitation with anti-lamin antisera , we conclude that the 68-kd isoprenylated protein found in nuclei from [ 14c ] mevalonate-labeled cho cells is lamin b .
