LigationAfter 3-fold overdigestion with enzyme 70% of DNA fragments can be ligated. Of these 80% can be recut.
Non-specific activityNo nonspecific activity was detected after incubation of 1 μg of T7 DNA with 1 u.a. of enzyme for 16 hours at 30C.
Optimum temperature30 oC
Inactivation 20 minutes65oC
Optimum SE-bufferY (33 mM Tris-acetate (pH 7.9 at 25C); 10 mM magnesium acetate; 66 mM potassium acetate; 1 mM DTT.) + BSA

Enzyme % activity:
0 - 100 - 100 - 100 - 10100

Note: To obtain 100% activity, BSA should be added to the 1x reaction mix to a final concentration of 100 ug/ml.
Do not use BSA for long incubation.
