Description
Inactivate endogenous nucleases when isolating RNA or DNA
Proteinase K from the fungus
Engyodontium album is a non-specific serine protease that is useful for general digestion of proteins.
- Over a wide pH range (optimal activity between 6.5 and 9.5)
- Under denaturing conditions (e.g., 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)
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.
Unit Definition:One mAnson unit is described as that amount of enzyme that liberates 1 µmole of Folin-positive amino acid within one minute at 37°C using hemoglobin as a substrate.
