| Source | E.coli strain, that carries the cloned gene Mfe I from Mycoplasma fermentans. |
| Assayed on | Lambda DNA |
| Unit definition | One unit of the enzyme is the amount required to hydrolyze 1 μg of Lambda DNA in 1 hour at 37°C in a total reaction volume of 50 μl. |
| Reaction buffer | SE-buffer B, (10 mM Tris-HCl (pH 7.6 at 25°C); 10 mM MgCl2; 1 mM DTT.) |
| Optimal temperature | 37oC |
| Storage conditions | 10 mM Tris-HCl (pH 7.6); 50 mM NaCl; 0,1 mM EDTA; 1 mM DTT; 200 μg/ml BSA; 50% glycerol. Store at -20°C. |
| Ligations | After 20-fold overdigestion with enzyme 90% of the 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 Lambda DNA with 20 u.a. of enzyme for 16 hours at 37°C.
|
| Reagents Supplied with Enzyme |
10 X SE-buffer B, BSA |
| Inactivation 20 minutes | No |
| 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.
