SourceFlavobacterium aquatile Ob10
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-bufferW (10 mM Tris-HCl (pH 8.5 at 25°C); 10 mM MgCl2; 100 mM NaCl; 1 mM DTT.) + SAM
Enzyme activity (%)
0 - 1025 - 5075 - 10010050 - 7570
Optimal temperature
Storage conditions10 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.
LigationsAfter 3-fold overdigestion with enzyme 20% of the DNA fragments can be ligated and of these 80% can be recut. In the presence of 10%PEG ligation is better.
Non-specific hydrolisisNo nonspecific activity was detected after incubation of 1 μg of Lambda DNA with 5 u.a. of enzyme for 16 hours at 37°C.
Reagents Supplied with Enzyme 10 X SE-buffer W, SAM
Methylation sensitivitynot tested
Inactivation 20 minutes under
NotesHigh enzyme concentration results in star activity
To obtain 100% activity, SAM should be added to a final concentration 0.01 mM
