Cusao Proteinase K, recombinant

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

Thermo Scientific Proteinase Okay is a broad-range endolytic protease extensively used for digestion of proteins in nucleic acid preparations. It degrades proteins even all through the presence of detergents. Proteinase Okay cleaves peptide bonds on the carboxylic sides of aliphatic, fragrant, 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 Basic Digestion of Protein in Pure Samples

  • Lively over a pH differ of 4.3–12.0, in 0.5% SDS or 1% Triton® X-100
  • Purified to take away RNase and DNase actions

Secure at Room Temperature and Straightforward to Use

  • Lively over pH differ 4.3–12.Zero in 0.5% SDS or 1% Triton X-100
  • Retains >80% prepare at temperatures as rather a lot as 60°C
  • No resuspension or thawing ahead of use
  • Cat.# MC5005, MC5008 provided at a highlight of 20mg/ml


Proteinase K, recombinant
Proteinase K, recombinant


• Prepared-to-use reply
• Lively in a variety 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

Keep in mind

• The really useful working focus of Proteinase Okay is 0.05 to 1 mg/mL. The prepare of the enzyme is stimulated by 0.2 to 1% SDS or by 1 to Four M urea
• Ca2+ protects Proteinase Okay in route of autolysis, will enhance the thermal stability, and has a regulatory perform for the substrate binding web site of Proteinase Okay
• Secure over an enormous pH differ: 4.Zero to 12.5, optimum pH 7.5 to eight.0
• Optimum prepare at 50 to55°C
• Speedy denaturation of enzyme happens at temperatures above 65°C.


Proteinase Okay Molecular Biology Grade from Parengyodontium album (Tritirachium album) is a subtilisin-related serine protease. It’s a broad-spectrum endopeptidase with a really excessive particular prepare.

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

Proteinase Okay Molecular Biology Grade (PCR Grade) is filled with life beneath a variety of response circumstances, together with elevated temperatures and the presence of SDS. In consequence, this enzyme is extensively utilizing for the digestion of proteins, together with DNases and RNases, all by nucleic acid preparations with out compromising the integrity of remoted DNA or RNA.


  • Recombinant broad-spectrum non-specific protease derived from Tritirachium album and over-expressed in Pichia pastoris.
  • Excessive prepare and distinctive purity.
  • Lively at excessive temperatures (as rather a lot as 56 °C) and denaturing circumstances (e.g. all through the presence of urea and/or SDS), which makes it best for digesting proteins in quite a lot of options.
  • Secure over an enormous pH differ: 4.0–12.5 (optimum pH 7.5–8.0).
  • Decreased quantity 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 fully completely totally different beginning offers.
  • Purification of goal provides from contaminating proteins.
  • Elimination of DNases and RNases all by nucleic acids isolation.
