| Optimal temperature | 37oC |
| Storage conditions | 10 mM Tris-HCl (pH 7.5); 250 mM NaCl; 0,1 mM EDTA; 7 mM 2-mercaptoethanol; 50% glycero; Store at -20°C. |
| Ligations | After 5-fold overdigestion with enzyme 70% 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 10 u.a. of enzyme for 16 hours at 37°C.

10 X SE-buffer B, BSA |
| Methylation sensitivity | not tested |
| Inactivation 20 minutes under | 65oC |
| Notes | To 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. |
