Conditions for 100% Activity:

  • 1X Buffer Cfr9I:10mM Tris-HCl (pH 7.2 at 37°C), 5mM MgCl2, 200mM sodium glutamate and 0.1mg/mL BSA
  • Incubate at 37°C

Storage Buffer:

  • Cfr9I is supplied in:10mM Tris-HCl (pH 7.5 at 25°C), 250mM KCl, 1mM DTT, 0.1mM EDTA, 0.2mg/mL BSA and 50% (v/v) glycerol

Ligation and Recleavage:

  • After 50-fold overdigestion with Cfr9I, more than 95% of the DNA fragments can be ligated and recut

Methylation Effects:

  • Dam: never overlaps-no effect
  • Dcm: never overlaps-no effect
  • CpG: completely overlaps-cleavage impaired
  • EcoKI: never overlaps-no effect
  • EcoBI: never overlaps-no effect

Digestion of Agarose-embedded DNA:

  • Minimum 5U of the enzyme are required for complete digestion of 1μg of agarose-embedded lambda DNA in 16 hours


To achieve complete digestion of substrate with Cfr9I, the concentration of DNA should be no less than 50μg/mL in the reaction buffer.
