DNase I, Bovine Pancreas (Lysate Tested), >500 Kunitz U/mg

Product Description

DNase I (Deoxyribonuclease I) is a dialyzed lyophilized powder from bovine pancreas that has been purified by chromatography.

Bovine pancreatic deoxyribonuclease (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 phosphate group at the 5' position. The optimum pH is 7.8.

DNase I is activated by bivalent metals, and inhibited by chelating agents such as EDTA and SDS. DNase I can be stabilized against proteolytic digestion by 5mM Ca2+.

MOLECULAR BIOLOGY GRADE

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

Storage/Handling: Store desiccated at -20°C.
Allow product to come to room temperature before opening.

For greatest stability, it is important that DNase to be dissolved at a concentration of at least 1 mg/ml in 50% Glycerol with 20mM Tris-HCl, pH 7.5, and 1mM MgCl2.
