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.
