Proteinase K

Proteinase K is a non-specific serine protease. This enzyme exhibits high stability and activity in the presence of SDS, EDTA and urea, as well as over a wide pH range. Proteinase K is useful for the inactivation of nucleases and lysis during the isolation of DNA and RNA.

Rnase A

RNase A is endonuclease-free and has been rigorously tested for RNA digestion activity in plasmid purification procedures.
