General description

Bovine pancreatic deoxyribonuclease I (DNase I) is a DNA minor grove-interacting nuclease which shows relatively low specificity. This protein is composed of two central ? sheets, each composed of six ?-strands. This structure is surrounded by extensive loop and ?-helical regions. This enzyme shares structural similarity to exonuclease III. DNase I is one of the most well characterized endonucleases of mammalian origin. It is a double-strand-specific endonuclease that requires bivalent cations for maximal activity.

For life science research only. Not for use in diagnostic procedures.

Preparation Note

Activator: Ca²⁺ (0.12 mM) in combination with Mg²⁺ enhances activity [Laskowski (1971); Melgar and Goldthwait (1968)].Working concentration: 1 mg/mlDo not vortex while dissolving!Storage conditions (working solution): Reconstituted in water, the solution can be kept for 2 to 3 days at 2 to 8 °C. Do not vortex during dissolving. Note: Dissolve at least 1 mg/ml.

Unit Definition

One unit is the enzyme activity that causes an increase in the absorbance of 0.001 per minute under assay conditions.
