Proteinase K Application

Proteinase K is stable in urea and SDS, and also has the ability to degrade natural proteins, so it is widely used, mainly used in gene diagnostic kits, genomic DNA extraction kits, RNA extraction kits to remove DNA and RNA preparation nucleic acids Enzymes can also be used to extract non-protein components in tissues to degrade protein-containing impurities. For example, the preparation of DNA vaccines and heparin.

Proteinase K Storage

The dry powder state can be stored at low temperature under the condition of 0~4℃. After dissolving, dispense into appropriate volume and store at -15℃-25℃. Transport can be carried out at room temperature.
Under the correct storage conditions, the dry powder state is valid for up to two years. The validity period of the liquid state at -15~25℃ is one year. After opening the package, please use it in time to prevent moisture absorption. After the solid enzyme is dissolved, it is recommended to filter and sterilize, divide it into an appropriate volume, and store at -15~25℃.
