on the basis of isodensity sedimentation of formaldehyde fixed particles in csc1 and of two-dimensional gel electrophoresis of ribosomal proteins , it appears that the native ribosomal subparticles contain a large protein complement than the derived subparticles and , correspondingly , they are less dependent on an external supply of initiation factors for haemoglobin synthesis in vitro .
