[Micromethod of ultracentrifugation in cesium chloride].
The micromethod of ultracentrifugation in cesium chloride is described. Band destributions have been analysed by the direct scanning of microtubes with the differential doublewave micro-spectrophotometer at 260 nm. The 10(-8)-10(-9) g of DNA or ribosomes are enough for one analysis, tube volume is 2 mul. The method described permits the simultaneous centrifugation of several probe scores. The error of the beyoant density determination is 0.001 g/sm3 relatively internal standard. DNA's from 5 types of Acetabularia were analysed by the developed technique.
