  • Title: Nuclear ribonucleoprotein complexes containing polyadenylate from mouse ascites cells.
    Author: Quinlan TJ, Billings PB, Martin TE.
    Journal: Proc Natl Acad Sci U S A; 1974 Jul; 71(7):2632-6. PubMed ID: 4368966.
    Abstract:
    Nuclear poly(A)-containing RNA of mouse ascites cells can be extracted in the form of 15-17S ribonucleoprotein complexes under conditions in which the bulk of the heterogeneous nuclear RNA is released as 30S complexes. The poly(A)-containing fraction of nuclear extracts has been resolved into two distinct components, 15 and 17 S; neither contains the two polypeptides of 30S ribonucleoprotein. The 17S particle contains approximately six polypeptide species of molecular masses 17,000-30,000 daltons. The 15S complex has four distinct polypeptides of higher molecular mass, including a prominent 80,000-dalton species.
