Proteinase K

A core nucleic acid pretreatment enzyme developed by directed evolution, with high activity, extreme guanidine salt tolerance and ultra-high purity. Free of impurity enzymes and background bacteria, it is suitable for nucleic acid extraction in conventional molecular experiments and high-end NGS/mNGS sequencing, and supports large-scale industrial supply.

Engineered by directed evolution, high activity and stability

Excellent tolerance to guanidine thiocyanate and guanidine hydrochloride

No impurity enzymes/heavy metal ions, DNA residue ＜5 pg/mg

No background bacterial contamination, ideal for NGS/mNGS
