  • MB112: Proteinase K Solution, PCR Grade

    Proteinase K is commonly used for protein digestion, DNA extraction, RNA purification, direct PCR, and genotyping. The recombinant proteinase K enzyme is a mutant to the native protease, which gains higher specific activity and yield as well as wider pH and temperature range . The large scale recombinant enzyme production has advantage in lot-to-lot consistency, superior purity and cost-efficiency. DNA-free nature of recombinant Proteinase K made it well-suited in isolating PCR and RT-PCR templates.
    High purity: Each lot of the recombinant proteinase K solution (molecular biology grade, PCR grade, NGS grade, chip grade, and RNA grade) was tested to ensure the absence of DNases and RNases, and free of DNA.
    The cheapest proteinase K solution in the market.
    Specific activity:  ≥ 780 units/ml.

  • MB111: Proteinase K Powder

    The recombinant proteinase K enzyme is a mutant to the native protease, which gains higher specific activity and yield as well as wider pH and temperature range . The large scale manufacturing of the recombinant enzyme has advantage in lot-to-lot consistency, superior purity and cost-efficiency. DNA-free nature of the recombinant Proteinase K made it well-suited in isolating PCR and RT-PCR templates.
    High purity: >99.5% by reducing SDS-PAGE. Each lot of the proteinase K powder was tested to ensure the absence of Nucleases and DNA. It can be used to make molecular biology grade proteinase K solution, PCR grade proteinase K solution, NGS grade proteinase K solution, CHIP grade proteinase K solution, and so on.
    Specific activity: ≥ 34 units/mg of protein.
    The lowest proteinase K price in the market.
