Unit definitionOne unit of the enzyme is the amount required to hydrolyze 1 μg of Lambda DNA in 1 hour at 50°C in a total reaction volume of 50 μl.
Assayed onLambda DNA
Storage conditions10 mM Tris-HCl(pH 7.5); 200 mM KCl; 0.1 mM EDTA; 7 mM 2-mercaptoethanol; 200 μg/ml BSA; 50% glycerol. Store at -20°C.
LigationAfter 5-fold overdigestion with enzyme more than 90% of the DNA fragments can be ligated and recut.
Nonspecific hydrolysisNo nonspecific activity was detected after incubation of 1 μg of Lambda DNA with 10 u.a. of enzyme for 16 hours at 50°C.
Methylation sensitivitynot tested
Reagents supplied with enzyme10 X SE-buffer B, BSA
NotesTo obtain 100% activity, BSA should be added to the 1 x reaction mix to a final concentration of 100 μg/ml Do not use BSA for long incubation.
