It is active under a wide range of reaction conditions, including elevated temperatures and in the presence of SDS. As a result, Proteinase K is widely used for the digestion of proteins, including DNases and RNases, during nucleic acid preparations without compromising the integrity of isolated DNA or RNA. Proteinase K is free of exonucleases, endonucleases, and ribonucleases.


  • Extraction of DNA and RNA from different starting materials
  • Purification of target material from contaminating proteins
  • Removal of DNases and RNases during nucleic acids isolation


  • Recombinant broad-spectrum non-specific protease derived from Tritirachium album and over-expressed in Pichia pastoris
  • Molecular Biology Grade
  • High activity and exceptional purity
  • Active at high temperatures (up to 56°C) and denaturing conditions (e.g. in the presence of urea and/or SDS), which makes it ideal for digesting proteins in variety of applications
  • Stable over a wide pH range: 4.0–12.5 (optimum pH 7.5–8.0)
  • Low residual DNA content (≤ 10 pg/mg).

Proteinase K is shipped on blue ice and should be stored at -20°C .
