title: [Properties of the rat liver DNA-dependent RNA-polymerase stored at -25 degrees C in the presence of glycerol or polyethyleneglycol-400].
abstract: The effect of slow freezing (1-2 degrees C/min) was studied as applied to the template activity of DNA in the RNA-polymerase reaction. It was found out that the activity of each RNA-polymerase form decreases after 24-hour storage by freezing at -25 degrees C in the presence of glycol or polyethylene glycol-400. The study of the enzyme in the glycerol concentration gradient showed sedimentation constant changes.
