Unit definitionOne unit of the enzyme is the amount required to hydrolyze 1 μg of Lambda DNA in 1 hour at 37°C in a total reaction volume of 50 μl.
Assayed onLambda DNA
Storage conditions10 mM Tris-HCl (pH 7.5); 200 mM NaCl; 0.1 mM EDTA; 1 mM DTT; 200 μg/ml BSA; 50% glycerol. Store at -20°C.
LigationAfter 10-fold overdigestion with enzyme 60% of the DNA fragments can be ligated and recut. In the presence of 10%PEG
Nonspecific hydrolysisNo nonspecific activity was detected after incubation of 1 μg of Lambda DNA with 10 u.a. of enzyme for 16 hours at 37°C.
Methylation sensitivitynot tested
Reagents supplied with enzyme10 X SE-buffer G, 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.
