|Ligations||After 20-fold overdigestion with enzyme more than 95% of the DNA fragments can be ligated and recut.|
|Non-specific hydrolisis||No nonspecific activity was detected after incubation of 1 μg of Lambda DNA with 50 u.a. of enzyme for 16 hours at 50°C.
|Reagents Supplied with Enzyme||
10 X SE-buffer W, BSA|
|Methylation sensitivity||not tested|
|Inactivation 20 minutes under||80oC|
|Notes||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.
