Source: Micrococcus luteus
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.
Assayed on:
Lambda DNA
Optimal SE-buffer: SE-buffer O
Enzyme activity (%):
B | G | O | W | Y | ROSE |
0 | 10 | 100 | 25 | 10 | 50 |
Storage conditions: 10 mM Tris-HCl (pH 7.5); 100 mM NaCl; 0.1 mM EDTA; 7 mM 2-mercaptoethanol; 200 μg/ml BSA; 50% glycerol; Store at -20°C.
Ligations:
After 20-fold overdigestion with enzyme 95% of the DNA fragments can be ligated and recut.
