Proteinase K: Powder and customized solutions
Proteinase K and the solution is used for protease digestion during DNA and RNA preparation. Proteinase K from GeneON is very active and stable, even at room temperature. As component in Diagnostics Kits or in DNA/RNA purification systems.
Digestion of proteins
Description:
Proteinase K is a serine protease that exhibits a very broad cleavage specificity. The Protein with a molecular weight 28.900 kD cleaves peptide bonds adjacent to the carboxylic group of aliphatic and aromatic amino acids. Proteinase K is not inactivated by chelating reagents such as EDTA or detergents such as SDS and is active over a wide range of pH (4-12.5).
Activity: > 30 units/mg protein (hemoglobin, pH 7.5, 37°C)
Unit definition:
Unit definition One unit is the amount of enzyme which releases at 37°C in 1 min as many folin-positive amino acids and peptides from hemoglobin as 1 μmol of tyrosine.
Features:
The protease or - its solution is a highly active and stable protease with low cutting specificity. The enzyme belongs to the group of subtilisine-related serine
proteases and is strongly inhibited by PMSF.
Usage:
In presence of 0.5 – 1 % SDS Proteinase inactivates DNases and RNases in eucaryotic and microbiological cell cultures. The use of Proteinase K during lysis of the cells allows the isolation of
intact highly-molecular nucleic acids.
Quality:
- purified by chromatography and lyophilised
- RNases: not detectable
- DNases: not detectable
- Exonucleases: not detectable
Storage:
4 °C or -20 °C for at least 24 months, shipment at ambient temperature
Storagebuffer: As an option GeneON offers: 50 mM Tris HCl (pH 8.0), 1 mM CaCl2, 50 % Gycerin (other buffers or other concentrations on request)
Custom aliquoting service
GeneON provides customized amounts of Proteinase K Powder and storage buffer on request. We precisely dispense Prot-K aliquots (liquid/lyophilized) that will fit the format of your choice.
Proteinase K isolated from Tritirachium album is used for protease digestion during DNA and RNA preparation. Proteinase K from GeneON is very active and stable. GeneON offers several sizes and sets of Proteinase K:
