Application: Used for the removal of nucleic acid from protein samples. Benzonase nuclease, or endonuclease from Serratia marcescens, can be used to degrade all forms of DNA and RNA while having no proteolytic activity. Benzonase nuclease can also be used to prepare proteins in microcalorimetric experiments Benzonase« is a genetically engineered endonuclease from Serratia marcescens. This endonuclease attacks and degrades all forms of DNA and RNA (single stranded, double stranded, linear and circular) and is effective over a wide range of operating conditions. The optimum pH for enzyme activity is 8.0-9.2. It completely digests nucleic acids to 5′- monophosphate terminated oligonucleotides 3 to 5 bases in length. This is ideal for removal of nucleic acids from recombinant proteins and for applications where complete digestion of nucleic acids is desirable. It also reduces viscosity in protein extracts and prevents cell clumping.

Unit Definition: One unit will digest sonicated salmon sperm DNA to acid-soluble oligonucleotides equivalent to a ΔA260 of 1.0 in 30 min at pH 8.0 at 37 ░C (reaction volume 2.625 ml).
Storage Buffer: Solution in 50% glycerol containing 20 mM Tris HCl, pH 8.0, 2 mM MgCl2, and 20 mM NaCl.
