Protocol

DNase I >2000 Kunitz U/mg

DNase I (Deoxyribonuclease I) is a dialyzed lyophilized powder from bovine pancreas that has been purified by chromatography. DNase is an endonuclease which splits phosphodiester linkages preferentially adjacent to a pyrimidine nucleotide yielding polynucleotides with a free hydroxyl group at the 3' position and a phosphate group at the 5' position.

One Kunitz unit will produce A260 of 0.001 per minute at pH 5.0 at 25°C using DNA, type I or III as the substrate.
