|Storage conditions||10 mM Tris-HCl (pH 7.5); 250 mM NaCl; 0.1 mM EDTA; 7 mM 2-mercaptoethanol; 200 μg/ml BSA, 50% glycerol; Store at -20°C.|
|Ligation||After 20-fold overdigestion with enzyme more than 90% of the DNA fragments can be ligated and recut.|
|Non-specific hydrolisis||No nonspecific activity was detected after incubation of 1 μg of Lambda DNA with 40 u.a. of enzyme for 16 hours at 37°C.
|Reagents Supplied with Enzyme||
10 X SE-buffer 2K, BSA|
|Methylation sensitivity||Blocked by Dam methylation (GmATC): TGATCA|
