[Nonribosomal ribonucleoprotein particles in preparations of nonhistone proteins extracted from pigeon erythroblast chromatin].
Two proteins were isolated from preparations of weakly bound nonhistone proteins, obtained from highly purified chromatin with 0.35 M NaCl. These two protein residues from chromatin RNP-particles have the buoyant density of 1.41 g/cm3 as shown by centrifugation in CsCl gradients and contain heterogeneous fast labelling nuclear RNA. According to SDS polyacrylamide gel electrophoresis the molecular weights of these proteins are 70000 and 43000 daltons.
