[Sorption of acid ribonuclease from Penicillium brevi-compactum by various ion-exchange resins].

Sorption of acid ribonuclease from Penicillium brevi-compactum F-399 was studied. The effect of nature and structure of various ion-exchange resins on the sorption capacity and reversibility was determined. High rate and reversibility of the enzyme sorption on the strong base anion-exchange fiber TsM-A2 were demonstrated. It is suggested that sorption of acid ribonuclease of the TsM-A2 fiber proceeds as ion exchange and on carboxyl cation exchange resins as molecular sorption.
