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 photolytic activity. Benzonase nuclease can also be used to prepare proteins in microcalorymetric experiments.
Digests native or heat-denatured DNA and RNA.
Benzonase® Nuclease is supplied by Merck KGaA and its affiliates.
