| 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. |
| 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 | | 75 - 100 | 75 - 100 | 10 - 25 | 10 - 25 | 100 | 40 |
|
| Optimal temperature | 37oC |
| Storage conditions | 10 mM Tris-HCl (pH 7.5); 250 mM NaCl; 0.1 mM EDTA; 7 mM 2-mercaptoethanol; 50% glycerol; Store at -20°C. |
| Ligations | After 5-fold overdigestion with enzyme about 5% of the DNA fragments can be ligated. Ligation is better in presence of 10% PEG. |
| 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.
