FAQ: Can Exonuclease I be used with a double stranded exonuclease to clean up plasmid preparations?

Exonuclease I can be used with Lambda Exonuclease (NEB# M0262) to clean up plasmid preps. Exonuclease III (NEB# M0206) and T7 Exonuclease (NEB# M0263) will also work, but will damage nicked plasmids.

Although Exonuclease I can be used, we recommend using Exonuclease V (RecBCD) to remove chromosomal DNA after plasmid prep.
