75 - 1001000 - 100 - 1075 - 1005
Optimal temperature
Storage conditions10 mM Tris-HCl (pH 7.5); 50 mM KCl; 0.1 mM EDTA; 7 mM 2-mercaptoethanol; 50% glycerol; Store at -20°C.
LigationAfter 5-fold overdigestion with enzyme > 90% of the DNA fragments can be ligated and recut.
Non-specific hydrolisisNo nonspecific activity was detected after incubation of 1 μg of Lambda DNA with 10 u.a. of enzyme for 16 hours at 37°C.
Reagents Supplied with Enzyme 10 X SE-buffer G, 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.
