The application of this Mutant Proteinase K is similar with wild type Proteinase K. But this mutant one has higher specific activity and more stable at room temperature. It is a non-specific serine proteinase with broad substrates. It is active over the pH range from 4 to 12. It can be used at any situation to digest native and denatured proteins. For instance, it is used for isolating mRNA or genomic DNA from different tissues and modifying glycoprotein for structure studies. Mutant Proteinase K is active with SDS, urea and EDTA and active between 15°C and 75°C.
We manufacture our proteinase k at industrial level with large fermentation tanks, which significantly reduces product cost. Buy with confidence, if the activity is lower than 30U/mg your money will be 100% refunded.
The shipping cost for each item ordered is $9.50, but will be automatically waived at checkout on orders of $200 and up.
