Description and Specification

Specification

For Use With (Application) Removal of endogenous nucleases during preparation of DNA and RNA; preparation of tissue sections for in situ hybridization
Quantity 5mL
Storage Requirements Store in freezer (-5° to -30°C).

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.
