title: [Isolation and purification of lactoperoxidase from cow's milk].
abstract: A procedure is described for isolation and purification of lactoperoxidase from cow milk. The procedure involved the following steps: isolation of casein from milk, sorption of lactoperoxidase on CM-Sephadex, concentration of the eluate using ultrafiltration, salting out with ammonium sulfate; isoelectric focusing was carried out in the borate-polyol system. Highly purified, active preparation of lactoperoxidase was obtained within a relatively short period by means of the procedure, where the available reagents were used.
