Proteinase K is a highly active 28,904-Da
serine protease isolated from the fungus
Tritirachium album. The enzyme exhibits
broad cleavage specificity on native and
denatured proteins and is widely used in the
purification of DNA and RNA. Its activity
is increased in the presence of denaturants
such as SDS (1%) and elevated temperature
(50-60°C). The recommended working
concentration is 50-100 µg/ml for protein
removal and enzyme inactivation, and up to
2 mg/ml for tissue treatment. The Proteinase K,
Lyophilized powder can be prepared as a
20 mg/ml stock solution in water and stored
in aliquots at -20°C. The enzyme is also
available as a ready-to-use concentrated stock
solution (600 mAU/ml) that is convenient
for routine use in most applications. 1 mg
of Proteinase K is the equivalent of 30 mAU
(AU = Anson unit). The Novagen Proteinase
K products are free of detectable DNase and
RNase
