Proteinase K is a highly active 28,904-Daserine protease isolated from the fungusTritirachium album. The enzyme exhibitsbroad cleavage specificity on native anddenatured proteins and is widely used in thepurification of DNA and RNA. Its activityis increased in the presence of denaturantssuch as SDS (1%) and elevated temperature(50-60C). The recommended workingconcentration is 50-100 µ,g/ml for proteinremoval and enzyme inactivation, and up to2 mg/ml for tissue treatment. The Proteinase K,Lyophilized powder can be prepared as a20 mg/ml stock solution in water and storedin aliquots at -20C. The enzyme is alsoavailable as a ready-to-use concentrated stocksolution (600 mAU/ml) that is convenientfor routine use in most applications. 1 mgof Proteinase K is the equivalent of 30 mAU(AU = Anson unit). The Novagen ProteinaseK products are free of detectable DNase andRNase
