    Recombinant Proteinase K


    Catalog Number:RPK09
    Alternate names:Protease K, Endopeptidase K, Tritirachium alkaline proteinas

    A serine protease that displays the ability to digest native proteins, thereby inactivating enzymes such as DNase and RNase without recourse to a denaturation process. It retains its activity in presence of SDS and urea. It is inactivated by diisopropyl fluorophosphates (DFP) and phenyl methane sulfonyl fluoride (PMSF).


    Format Lyophilized
    M.W 29.3kD
    Purity 99%
    Activity 30 units/mg
