Proteinase K Molecular Biology Grade from Parengyodontium album (Tritirachium album) is a subtilisin-related serine protease. It is a broad spectrum endopeptidase with a very high specific activity. Proteinase K Molecular Biology Grade is active under a wide range of reaction conditions, including elevated temperatures and presence of SDS. As a result, this enzyme is widely using for digestion of proteins, including DNases and RNases, during nucleic acid preparations without compromising the integrity of isolated DNA or RNA. Proteinase K Molecular Biology Grade is free of exonucleases, endonucleases, and ribonucleases. Also check our Proteinase K NGS Grade

PROTEINASE K Molecular Biology Grade from Parengyodontium album (Tritirachium album) is a subtilisin-related serine protease

This recombinant enzyme is expressed in Pichia pastoris, and undergoes extensive purification to yield the highest quality 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 (e.g. in the presence of urea and/or SDS), what 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).
  • Decreased amount of host DNA (≤ 10 pg/mg / MBG or ≤ 0.1 pg/mg NGS).
  • Available as powder, lyophilized “cake” or liquid.

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.

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.

BLIRT Proteinase K Molecular Biology Grade

Activity

Proteinase K MBG - Activity

Blirt’s Proteinase K MBG is interchangeable with comparators without dose adjustments.
Declared activity for all shown suppliers is ≥30 U/mg (blue line).

Stability

 

Blirt’s Proteinase K MBG shelf life is guaranteed up to 2 years (storage at -20°C).

 

Recommended storage of MBG Proteinase K Solution is -20°C

Temporary exposures to temperature (tested at +37 ° C) changes e.g. during transportation or experiments bring no differences in protein activity.

Consistency

Automation of the Proteinase K MBG Production results in minimal batch to batch activity variation.

Consistency in the product characteristics in all delivered batches guarantees reliable experiments results and stable working conditions.

Blue line represents declared minimum activity (≥ 30 U/mg). Batch-to-batch variation is 3,0% (with measurement error ± 1-6%).
