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 β sheets, each composed of six β-strands. This structure is surrounded by extensive loop and α-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.
Application
Isolation procedures for proteins (e.g., membrane proteins).
Bovine pancreatic deoxyribonuclease I (DNase I) has been used for-
Bovine pancreatic deoxyribonuclease I (DNase I) has been used for-
- The isolation of cells from lung, skin and tumor samples
- Bacterial DNA extraction from live bacterial cells that are resistant to DNase I †
Unit Definition
One unit is the enzyme activity that causes an increase in the absorbance of 0.001 per minute under assay conditions.
Preparation Note
Activator: Ca2+ (0.12 mM) in combination with Mg2+ enhances activity [Laskowski (1971); Melgar and Goldthwait (1968)].
Working concentration: 1 mg/ml
Do 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.

Human lungs are constantly exposed to bacteria in the environment, yet the prevailing dogma is that healthy lungs are sterile. DNA sequencing-based studies of pulmonary bacterial diversity challenge this notion. However, DNA-based microbial analysis currently fails to distinguish between DNA...
