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

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 preparation 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.
