Cat No.

NATZ-112

Description

Proteinase K is a serine protease, sourced from Parengyodontium album (formerly known as Tritirachium album). It exhibits robust activity across a broad range of conditions, including high temperatures and environments containing Sodium Dodecyl Sulfate (SDS).
As a versatile endopeptidase with exceptional specific activity, Proteinase K efficiently degrades proteins, including DNases and RNases, during nucleic acid extraction processes. This ensures the integrity of isolated DNA or RNA remains intact.
Produced through expression in Pichia pastoris, Proteinase K is rigorously purified to eliminate any traces of exonucleases, endonucleases, and ribonucleases, making it highly suitable for sensitive molecular biology applications.
