The isolation and properties of a ribonuclease associated with influenza virus

A ribonuclease activity associated with influenza virus has been purified to homogeneity. This preparation is free of DNAase, phosphodiesterase, and phosphatase activities. The purified enzyme has a pH optima of 7.0 at 37 degrees C, and moves as a single band on sodium dodecyl sulfate - polyacrylamide gel with an estimated molecular weight of 84 000.
