Invitrogen™ Proteinase K Powder
Description
Proteinase K from the fungus Engyodontium album is a non-specific serine protease that is useful for general digestion of proteins.
Proteinase K Remains Active:
• 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.

Frequently Asked Questions (FAQs)
Scrape a single colony from the surface of an agar plate and transfer to 12 µL of SCL solution [10 mM Tris-HCl (pH 7.5), 1 mM EDTA, 50 µg/mL proteinase K] and incubate for 15 min at 55 degrees C. Inactivate proteinase K for 15 min at 80 degrees C and add 20 µL of deionized water. Centrifuge at 12,000 x g for 3 min. Transfer the supernatant to a new tube.
