Abstract

Abstract The comparative protein composition of L-cell messenger ribonucleo-proteins (mRNPs) was studied as a function of mRNP isolation methodology. Proteins with approximate molecular weights of 75,000, 50,000, 46,000 and 34,000 were common to mRNPs prepared by three methods: (1) isopycnic gradient centrifugation in Cs 2SO 4, (2) binding to poly(U)-glass fiber filters, or (3) oligo-deoxythmidylate cellulose chromatography.
