Enzyme activity (%)
BGOWYRose
50 - 7510 - 2510 - 2575 - 10050 - 7530
Optimal temperature
37oC
Storage conditions10 mM Tris-HCl (pH 7.5); 50 mM KCl; 0.1 mM EDTA; 7 mM 2-mercaptoethanol; 200 μg/ml BSA; 50% glycerol.
Store at -20°C.
LigationsAfter 10-fold overdigestion with enzyme more than 95% 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 K, BSA
Methylation sensitivitynot tested
Inactivation 20 minutes under
65oC
NotesHigh enzyme concentration may result in star activity
To obtain 100% activity, BSA should be added to the 1x reaction mix to a final concentration of 100 μg/ml.
Do not use BSA for long incubation.
