Assayed onLambda DNA
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.
Optimal SE-bufferB (10 mM Tris-HCl (pH 7.6 at 25°C); 10 mM MgCl2; 1 mM DTT.) + BSA
Enzyme activity (%)
10050 - 750 - 100 - 1050 - 755
Optimal temperature
Storage conditions10 mM Tris-HCl (pH 7.5); 50 mM KCl; 0.1 mM EDTA; 10 mM 2-mercaptoethanol; 200 μg/ml BSA; and 50% glycerol.
Storage temperature: -20°C.
For long term storage (more than 30 days), store at -70°C.
LigationsAfter 10-fold overdigestion with enzyme more than 90% of the DNA fragments can be ligated and recut. Ligation is better in presence of 10% PEG.
Non-specific hydrolisisNo 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 B, BSA
Methylation sensitivitynot tested
Inactivation 20 minutes under
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.
