* Star activity appears at a greater than 5-fold overdigestion (5 units x 1 hour).

Storage Buffer
10 mM Tris-HCl (pH 7.5 at 25°C), 100 mM KCl, 1 mM DTT, 0.1 mM EDTA, 0.2 mg/ml BSA and 50% glycerol.

Ligation and Recleavage
After 10-fold overdigestion with AasI, more than 95% of the digested DNA fragments can be ligated and recut.

Methylation Effects
Dam: Dcm: CpG: EcoKI: EcoBI:	never overlaps  never overlaps  may overlap  never overlaps  never overlaps	- no effect. - no effect. - cleavage impaired. - no effect. - no effect.

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
Greater than 10-fold overdigestion with AasI may result in star activity.
