[The purification of beta-galactosidase by flow electrophoresis]

A plant has been constructed for the free-flow electrophoresis. It permits carrying out electrophoretic separation both in a free flow and with the use of neutral grained fillers. Beta-galactosidase has been purified from the culture liquid of the Escherichia coli cell phage lysate. Its content in the purified material amounted to 81.2
