title: Phenol extraction of 28 S ribosomal RNA from rat liver cytoplasm.
abstract: A simple and reproducible phenol method for the isolation of 28 S ribosomal RNA from rat liver cytoplasm, free from poly(A)+/-RNA is described. The procedure is based on the observation that at lower pH of the homogenate (pH 5.5) 28 S ribosomal RNA is extracted, while 18 S ribosomal RNA remains in the interphase layer.
