title: Characteristics of messenger ribonucleoprotein and putative messenger RNA from Ehrlich ascites tumor cells.
abstract: Ehrlich ascites tumor cell messenger ribonucleoprotein (mRNP) and putative messenger RNA (mRNA) were isolated under conditions minimizing RNA degradation by ribonucleases and non-specific protein-RNA interaction, mRNP dissociated from polysomes by puromycin and EDTA sedimented to 185S. Putative messenger RNA released by proteinase K sedimented from 50 to 97S, with a maximum molecular weight approximating 6-25 X 10(6) daltons.
