Storage Buffer
10 mM Tris-HCl (pH 7.4 at 25°C), 300 mM NaCl, 10 mM MgCl2, 1 mM DTT, 0.15% Triton X-100, 0.2 mg/ml BSA and 50% glycerol.

Ligation and Recleavage
After 50-fold overdigestion with SfiI, 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
  • Assayed using Adenovirus-2 DNA.

  • Incubation at 37°C results in 10% activity.

  • For cleavage with SfiI at least two copies of its recognition sequence are required.
