Features Proteinase K isolated from Tritirachium album is used for protease digestion during DNA and RNA preparation. It is a serine protease that exhibits broad cleavage specificity. With a molecular weight 28.900 kD, it cleaves peptide bonds adjacent to the carboxylic group of aliphatic and aromatic amino acids.Proteinase K is not inactivated by chelating reagentssuch as EDTA or detergents such as SDS and is active over a wide range of pH (4-12.5). Advantages & Features : Highly active and stable : > 30 units/mg protein (hemoglobin, pH 7.5, 37°C). High Quality : free of RNases, DNases and Exonucleases contamination. Purified by chromatography. Lyophilised format. Low cutting specificity. Applications : Isolation of genomic DNA from cultured cells and tissues. Removal of DNases and RNases during DNA and/or RNA purification. Determination of enzyme locations.
