Proteoglycan subunits from human articular cartilage were fractionated by caesium sulphate density gradient centrifugation. A single heterogeneous population of molecules was produced whose average density decreased with increasing age of the individual from which they were obtained. At no density

Upon CS2SO4 density-gradient equilibrium centrifugation, 60S subunits of rat liver ribosomes were dissociated to form three bands at the densities of 1.55, 1.40, and 1.30 g/ml. The bands at 1.55 and 1.30 g/ml were shown to contain exclusively RNA or

Soaking crystals of rhodanese (thiosulphate:cyanide sulphurtransferase) in 2 M caesium sulphate reveals three caesium binding sites of this enzyme. One of these had been described before as a binding site for sodium ions and is located in a cleft close

A procedure for the purification of viroid RNA from tomato plants is described which yields up to a milligram of viroid RNA of gel electrophoretic homogeneity within 2 days. This technique is at least three times as fast as previous

When frog skeletal muscle fibres are bathed in solutions containing Cs(+) and K(+) in the ratio 1:4,000, a reduction is observed in the size of inward K currents through the resting membrane. This effect is enhanced by an increase in
