Product Description
Solution (~ 2 Kunitz units/ml). RNase & Protease free.
Biological function
Bovine pancreatic deoxyribonuclease is an endonuclease which splits phosphodiester linkages, preferentially adjacent to a pyrimidine nucleotide yielding polynucleotides with free hydroxyl group at the 3' position and phosphate group at the 5' position.
Host
Bovine
Theoretical MW (kDa)
31.3
Form
Liquid
Preparation Method
Native protein chromatographically purified from Bovine Pancreas
Concentration
~ 1 mg/mL
Activity
>=2,000 Kunitz units per ml. One Unit causes an increase in absorbance at 260 nm of 0.001 per minute per ml at 25°C when acting upon highly polymerized DNA at pH 5.0.
