Purpose

  • To digest (Adeno) methylated GATC sites. Useful for removing cell-derived plasmid template from PCR samples.

Procurement

  • Can be ordered from NEB.
  • Typically stored at -20°C.

Use

  • Use in NEBuffer 4. However, can be added directly to PCR sample.
  • Incubate at 37°C.
  • Heat inactivate by incubating at 80°C for 20 minutes.
  • DpnI cleaves hemi-adenomethylated dam sites 60X more slowly than fully methylated. NEB FAQ
  • Plasmids derived from Dam+ e.coli strains will be a substrate

Relevant protocols

Safety

  • None known.
