title: [Preparation and study of properties of immobilized phosphodiesterases from blunt-nosed viper venom].
abstract: From gurza poison phosphodiesterase covalently bound with DEAE-cellulose via triazine dye was isolated. Immobilized phosphodiesterase retained 100% activity of the initial enzyme. The effect of pH, temperature. Mg++ concentration on the immobilized enzyme activity was studied. Preparations of the immobilized enzyme did not lose their activity upon hydrolysis of oligodeoxy- and ribonucleotides during a month and remained suitable for prolonged hydrolysis of preparative quantities of oligonucleotides.
