Invitrogen™ Proteinase K Solution (20 mg/mL), RNA grade - 25-530-049/25530049

Invitrogen™ Proteinase K Solution (20 mg/mL), RNA grade - 25-530-049/25530049

Description

Proteinase K from the fungus Engyodontium album is a nonspecific 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., 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.

Unit definition
One mAnson unit is described as that amount of enzyme that liberates 1µmole of Folin-positive amino acid within one minute at 37°C using hemoglobin as a substrate.
