Storage Buffer
 10 mM Tris-HCl (pH 7.5 at 25°C), 250 mM KCl, 1 mM DTT, 0.1 mM EDTA, 0.2 mg/ml BSA and 50% glycerol.

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

Digestion of Agarose-embedded DNA
Minimum 5 units of the enzyme are required for complete digestion of 1 µg of agarose-embedded lambda DNA in 16 hours.

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