[A new method of isolating lysyl-tRNA-synthetase from the rat liver]

The methods of gel filtration on sepharose 6B, hydrophobic chromatography, chromatofocusing were used to isolate the preparation of lysyl-tRNA-synthetase. The enzyme activity at the terminal stage of purification is 1800 times as high. The isolated preparation is homogeneous with electrophoresis in 4-30% PAAG.
