| Source | Bacillus stearothermophilus MW |
| 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 55°C in a total reaction volume of 50 μl. |
| Optimal SE-buffer | Y (33 mM Tris-acetate (pH 7.9 at 25°C); 10 mM magnesium acetate; 66 mM potassium acetate; 1 mM DTT.) |
| Enzyme activity (%) | | B | G | O | W | Y | R | | 10 - 25 | 25 - 50 | 25 - 50 | 50 - 75 | 100 | 40 |
|
| Optimal temperature | 55oC |
| Storage conditions | 10 mM Tris-HCl (pH 7.5); 50 mM KCl; 0.1 mM EDTA; 200 μg/ml BSA, 7 mM 2-mercaptoethanol; and 50% glycerol. Store at -20°C. For long term storage (more than 7 days), store at -70ºC. |
| Ligations | After 5-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 10 u.a. of enzyme for 16 hours at 55°C.
