QIAamp DNA Blood Mini, Midi and Maxi Kits.QIAGEN Protease is supplied in the following QIAGEN kits: QIAGEN Protease is completely free of DNase and RNase activities. It is an economical alternative to Proteinase K for isolation of native DNA and RNA from a variety of sources. QIAGEN Protease is a serine protease isolated from a recombinant Bacillus strain.
Proteinase K is supplied in the following QIAGEN kits: This means that EDTA, which is used to inhibit Mg2+-dependent enzymes such as nucleases, will not inhibit Proteinase K activity.
Soluble calcium is not essential for enzymatic activity. It possesses a high specific activity that remains stable over a wide range of temperatures and pH values with substantially increased activity at a higher temperature. QIAGEN Proteinase K is a subtilisin-type protease isolated from the saprophytic fungus Tritirachium album and is particularly suitable for short digestion times. One mAU is the activity that releases folin-positive amino acids and peptides corresponding to 1 µmol tyrosine per minute
