Product details


Proteinase K (from Tritirachium album) is a non-specific protease of the serine protease family.
Proteinase K is used for the cleavage of proteins in nucleic acid preparations. It is mainly used in nucleic acid purification or for the removal of nucleases.
Proteinase K is active under a wide range of reaction conditions, including elevated temperatures and presence of SDS.


Directions for use

Activity: (Haemoglobin, pH 7.5; 25 °C) 30 mAnson-U/mg
Foreign activity: RNase and DNase not detectable
Optimum temperature: +65 °C.
Activity at +65 °C is ca. 12 x higher than at +25 °C. Over +65 °C, inactivation due to denaturation.
Activators: Denaturating agents like SDS (0,5-1 %), urea.
Inhibitors: Inhibition with Hg2+-ions, DFP, PMSF and phenol. Not inhibited by EDTA, sulfhydryl reagents and trypsin or chymotryps ininhibitors.
Stability: pH 4.0-12.5. pH optimum: 8,0.
Also stable even when denaturing agents, e.g. SDS and urea are present.
Stabilisers: Ca2+-ions (1-5 mM) prevent autolysis.


Working concentration

Stock solution: 20 mg/ml in water
Storage temperature (stock solution): -20 °C
Reaction buffer: 50 mM Tris-HCl; pH 7.5; 5 mM CaCl2; 0.5 % SDS
Working solution: 50 µg/ml



Proteinase K ≥30 mAnson U/mg, lyophilized

A non-specific protease with strong proteolytic activity for degrading proteins in biological samples. A quality product for molecular biology with a broad scope of application.

Application examples:
  • Preparing chromosomal DNA for PFGE
  • Degrading nucleases during preparation of nucleic acids (includes preparation of native RNA)

Art. No. 7528.3: A stock solution with a concentration of 20 mg/ml can be prepared directly by adding 25 ml buffer or water.

General information

Enzyme: a neoclassical, Greek artificial word ενζυμου, énzymon, derived from εν-, en- (in-) and ζυμη, zýmé (yeast, sourdough, archaic)
Ferments: comes from the Latin fermentum (ferments, sourdough)

There are six classes in which all enzymes are classified according to the particular reaction they catalyse:
Oxidoreductases (catalyse redox reactions)
Transferases (transfer functional groups among substrates)
Hydrolases (cleave bonds via addition of water)
Lyases/Synthases (cleave or synthesise complex products out of basic substrates without cleavage of ATP)
Isomerases (transform chemical isomers)
Ligases/Synthetases (cleave or synthesise complex products out of basic substrates via cleavage of ATP)
