Optimal temperature | 37oC |
Storage conditions | 10 mM Tris-HCl (pH 7.5); 100 mM KCl; 0.1 mM EDTA; 7 mM 2-mercaptoethanol; 200 μg/ml BSA; 50% glycerol. Storage at -20°C. Storage at -70°C is recommended for periods longer than 7 days. |
Ligation | After 3-fold overdigestion with enzyme > 95% of Ad2 DNA fragments can be ligated with T4 DNA Ligase and recut. |
Non-specific hydrolisis | No nonspecific activity was detected after incubation of 1 μg of Ad2 DNA with 4 units of enzyme for 16 hours at 37°C.

Reagents Supplied with Enzyme |
10 X SE-buffer RigI, BSA |
Methylation sensitivity | Blocked by mCG or GmC methylation:
5`-GGC(m5C)GGCC-3`/3`-CCGG(m5C)CGG-5` or
5`-GG(m5C)CGG(m5C)C-3`/3`-C(m5C)GGC(m5C)GG-5`
|
Inactivation 20 minutes under | 65oC |
Notes | Do not use BSA for long incubation.
To obtain 100% activity, BSA should be added to the 1 x reaction mix to a final concentration of 100 μg/ml. |
