TurboNucleaseTM is an ultra-pure recombinant form of Serratia marcescens extracellular endonuclease (encoded by the same gene as Benzonase) produced in E. coli using a proprietary process. This non-specific endonuclease hydrolyzes both single- and double-stranded nucleic acids (DNA and RNA) to 5’-phosphorylated oligonucleotides of 1-4 bases in length. TurboNuclease is a highly purified homodimer of 27 kDa subunits that has exceptionally high specific activity and is free of protease activity. TurboNuclease is ideal to digest nucleic acids and to reduce viscosity during protein purification and sample preparation.

One unit of TurboNuclease converts 1.0 OD260 of salmon sperm DNA into acid-soluble nucleotides in 30 minutes at 37oC in a reaction buffer of 50 mM Tris-HCl, pH 8.0 and 1 mM MgCl2. This corresponds to complete digestion of 50 µg of salmon sperm DNA into oligonucleotides. TurboNuclease has similar specific activity as Benzonase
