Proteinase K, MB and NGS Grade
- High activity and exceptional purity
- Active at high temperatures and denaturing conditions
- From Parengyodontium album (Tritirachium album)
- Free of exonucleases, endonucleases, and ribonucleases
- Lyophilized or as a solution (MB grade only)
Proteinase K, MB and NGS Grade
Why proteinase K ?
- It is a broad spectrum endopeptidase with a very high specific activity
- It is active under a wide range of reaction conditions, including elevated temperatures and presence of SDS
- It does not compromise the integrity os isolated DNA or RNA during nucleic acid preparations
- It is free of exonucleases, endonucleases, and ribonucleases
- Proteinase K NGS Grade: an extra purification step results in significantly increased solubility (2.5 fold), increased specific activity, and decreased DNA content, compared to ou Molecular Biology Grade product.
Features
- Recombinant broad-spectrum non-specific protease derived from Tritirachium album and over-expressed in Pichia pastoris
- High activity and exceptional purity
- Active at high temperatures (up to 56°C) and denaturing conditions
- Stable over a wide pH range: 4.0–12.5 (optimum pH 7.5–8.0)
- Decreased amount of host DNA (≤ 10 pg/mg / MBG or ≤ 0.1 pg/mg NGS)
- Units: One unit of Proteinase K hydrolyzes urea-denaturated hemoglobin producing color equivalent of 1 μmol tyrosine per 1 min at 37°C and pH 7.5 (Folin & Ciocalteu’s method), 1 U = 1 mAnsonU
Applications
- 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
That's how important proteinase K is
- Proteinase K is a widely used enzyme to digest proteins in various applications such as nucleic acid isolation and purification
- The isolated material is used in a variety of experiments and diagnostic applications
- The quality of this basic enzyme guarantees the success of the whole experiment
