| Abstract: | The three methods most commonly used for removing RNase from preparations of DNase were compared under similar assay conditions for residual RNase activity. In order of their effectiveness they ranked: (1) bentonite, (2) agarose-UMP, (3) iodoacetate. Even the best of the single treatments did not eliminate all of the RNase, and it was discovered that a significant improvement was obtained when DNase was first passed over agarose-UMP and then treated with bentonite. |
