10mM Tris-HCl (pH 7.4 at 25°C), 100mM KCl, 7mM 2-mercaptoethanol, 1mM EDTA, 0.2mg/ml BSA and 50% (v/v) glycerol
Ligation and Re-cleavage:
More than 95% of the DNA fragments can be ligated and re-cut after a 50-fold over-digestion with XbaI.
Digestion of Agarose-embedded DNA:
A minimum 5 units of XbaI is required for the complete digestion of 1μg of agarose-embedded lambda DNA in 16 hours.
- XbaI is blocked by overlapping dam methylation.
- To avoid dam methylation, use a dam-, dcm- strain.
Dam: May overlap - blocked
- 5'...TCTAGm6A TC...3'
- 3'...AGATC Tm6AG...5'
- (Cleavage is blocked)
CpG: Never overlaps - no effect
EcoKI: Never overlaps - no effect
EcoBI: Never overlaps - no effect
