Cusao Proteinase k

Proteinase K, recombinant

Proteinase Okay – one of many usually used enzymes in molecular biology.

Glorious different for protein digestion in various features.

  • BLIRT – skilled in Proteinase Okay manufacturing for over 15 years.
  • Licensed manufacturing course of ISO 13485 ensuing inside the highest top quality product with a extremely low batch-to-batch variability.
  • Large parts, the chance of white labeling, and portioning service – liquid type inside the amount on the customer’s request (as a lot as a lot of million samples month-to-month).

Thermo Scientific Proteinase Okay is a broad-range endolytic protease extensively used for digestion of proteins in nucleic acid preparations. It degrades proteins even inside the presence of detergents. Proteinase Okay cleaves peptide bonds on the carboxylic sides of aliphatic, aromatic, or hydrophobic amino acids. The Proteinase Okay is classed as a serine protease. The smallest peptide to be hydrolyzed by this enzyme is a tetrapeptide.

Proteinase Okay (Lyophilized)

For Primary Digestion of Protein in Natural Samples

  • Energetic over a pH range of 4.3–12.0, in 0.5% SDS or 1% Triton® X-100
  • Purified to remove RNase and DNase actions

Safe at Room Temperature and Easy to Use

  • Energetic over pH range 4.3–12.Zero in 0.5% SDS or 1% Triton X-100
  • Retains >80% train at temperatures as a lot as 60°C
  • No resuspension or thawing sooner than use
  • Cat.# MC5005, MC5008 supplied at a spotlight of 20mg/ml


• Ready-to-use reply
• Energetic in a wide range of response circumstances


• Isolation of genomic DNA from mouse tail
• Isolation of genomic DNA from cultured cells
• Elimination of DNases and RNases when isolating DNA and RNA from tissues or cell traces
• Dedication of enzyme localization
• Enhancing cloning effectivity of PCR merchandise


• The actually helpful working focus of Proteinase Okay is 0.05 to 1 mg/mL. The train of the enzyme is stimulated by 0.2 to 1% SDS or by 1 to 4 M urea
• Ca2+ protects Proteinase Okay in the direction of autolysis, will enhance the thermal stability, and has a regulatory carry out for the substrate binding site of Proteinase Okay
• Safe over a big pH range: 4.Zero to 12.5, optimum pH 7.5 to eight.0
• Optimum train at 50 to55°C
• Speedy denaturation of enzyme occurs at temperatures above 65°C.

Proteinase Okay Molecular Biology Grade from Parengyodontium album (Tritirachium album) is a subtilisin-related serine protease. It is a broad-spectrum endopeptidase with a extremely extreme specific train.

Recombinant Proteinase Okay enzyme is expressed in Pichia pastoris, and undergoes in depth purification to yield the perfect top quality product.

Proteinase Okay Molecular Biology Grade (PCR Grade) is energetic beneath a wide range of response circumstances, along with elevated temperatures and the presence of SDS. In consequence, this enzyme is extensively using for the digestion of proteins, along with DNases and RNases, all through nucleic acid preparations with out compromising the integrity of isolated DNA or RNA.


  • Recombinant broad-spectrum non-specific protease derived from Tritirachium album and over-expressed in Pichia pastoris.
  • Extreme train and distinctive purity.
  • Energetic at extreme temperatures (as a lot as 56 °C) and denaturing circumstances (e.g. inside the presence of urea and/or SDS), which makes it highest for digesting proteins in a variety of features.
  • Safe over a big 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).
  • Accessible as powder, lyophilized “cake” or liquid.


  • Extraction of DNA and RNA from completely completely different starting provides.
  • Purification of objective supplies from contaminating proteins.
  • Elimination of DNases and RNases all through nucleic acids isolation.
