Proteinase K, Tritirachium album limber


Chemische Eigenschaften

Lyophilized powder, 28.9 kDa
Storage & Sensitivity
Keep Cold.
It is fully miscible with water.


Proteinase K is commonly used in molecular biology to digest protein and remove contamination from preparations of nucleic acid. Addition of Proteinase K to nucleic acid preparations rapidly inactivates nucleases that might otherwise degrade the DNA or RNA during purification. Proteinase K is specifically formulated for molecular cloning, nucleic acid research and protein/peptide structural analysis, inactivation of Rnase and Dnases, isolation of high molecular weight DNA, isolation of RNA or the isolation of plasmid and genomic DNA. Proteinase K is used for the isolation of native high molecular genomic nucleic acids.


Minimum 20 units per mg dry weight. One unit releases one micromole of Folin positive amino acids, measured as tyrosine, at 37 C and pH 7.5, using urea denatured hemoglobin as the substrate
