- Under denaturing conditions–e.g., in the presence of SDS or urea
- In the presence of metal chelating agents–e.g., EDTA
- At comparatively high temperatures–optimum digestion temperature is 65°C
- Protein Filter: P
Applications
Removal of endogenous nucleases during the preparation of DNA and RNA; preparation of tissue sections for in situ hybridization.
Performance and quality testing
Endodeoxyribonuclease and exodeoxyribonuclease assays; liquid form tested for absence of RNase activity.
