Free polyribosomes, isolated from liver, spleen and pancreas of the rat, were suspended in a medium at 0.5 mM Mg2+ and analyzed in the analytical ultracentrifuge. The percentage of run-off ribosomes, distinguised by a sedimentation coefficient below 77S was calculated from centrifugal experiments. The amount of run-off ribosomes differed in the various tissues of the rat but was not influenced by fasting overnight.
