Conditions for 100% Activity:
1X Buffer G:10mM Tris-HCl (pH 7.5 at 37°C), 10mM MgCl2, 50mM NaCl and
0.1mg/mL BSA
Incubate at 37°C
Storage Buffer:
Eco31I is supplied in:10mM Tris-HCl (pH 7.5 at 25°C), 200mM KCl, 1mM
DTT, 0.1mM EDTA, 0.2mg/mL BSA and 50% (v/v) glycerol
Ligation and Recleavage:
After 50-fold overdigestion with Eco31I, more than 95% of DNA
fragments can be ligated and recut
Methylation Effects:
Dam: never overlaps-no effect
Dcm: may overlap-cleavage impaired
CpG: may overlap-cleavage impaired
EcoKI: never overlaps-no effect
EcoBI: may overlap-effect not determined
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
Note:
Assayed using lambda DNA (dcm-) (#SD0021), as one of the two Eco31I
recognition sites in lambda DNA is difficult to cleave. Eco31I cleavage is
impaired by overlappingdcm methylation. To avoiddcm methylation, use adam,dcm-
strain such as GM2163 (#M0099). Low salt, high glycerol (>5%)
concentrations, pH >8.0 or a large excess of enzyme may result in star
activity. Eco31I cleaves downstream of its recognition site and can generate
any desired 4 base 5'-overhangs. This feature is useful for direct PCR product
cloning.
