FIELD: medicine; biology; pharmacology. SUBSTANCE: sturgeon soft roe is homogenized to perform DNA deproteinization directly in homogenizate, the mixture is treated with sodium chloride solution at 50-60 C, then it is treated with Kieselguhr, concentrated by using electrodialyser or in membrane apparatus and exposed to sonic waves. DNA is precipitated with alcohol and dried in drying cabinet at 40 C. EFFECT: enhanced effectiveness of industrial DNA production.
