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-
  • 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

Insulin-like growth factor binding protein 3 (IGFBP3), a hypoxia-inducible gene, regulates a variety of cellular processes including cell proliferation, senescence, apoptosis and epithelial-mesenchymal transition (EMT). IGFBP3 has been linked to the pathogenesis of cancers. Most previous studies focus upon proapoptotic

Studying skin immune cells under various pathophysiological conditions is vital for understanding the nature of cutaneous inflammatory responses. Available methods of isolating cells from the skin have relatively low yield or require in vitro culture. To increase the effective isolation

Pulmonary eosinophilia is a consistent hallmark of allergic lung inflammation. Infiltration of eosinophils into ovalbumin (OVA)-challenged lungs is dependent on the adhesion molecule vascular cell adhesion molecule-1 (VCAM-1) on endothelial cells. Ligation of VCAM-1 activates endothelial cell protein tyrosine phosphatase

Alveolar macrophages (AMs) obtained by bronchoalveolar lavage (BAL) are commonly used to study lung macrophage-mediated immune responses. Questions remain, however, about whether AMs fully represent macrophage function in the lung. This study was performed to determine the contribution of interstitial
