Recombinant Salt Active SuperNuclease is a nonspecific endonuclease from a halophilic microorganisms, which is produced in E. coli. Because of the high affinity with cation exchange resins, this enzyme can be removed easily from biological samples such as adeno-associated virus (AAV) and lentivirus. Salt Active SuperNuclease has optimal activity at salt concentrations between 350~650 mM.
