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.
Assayed on Lambda DNA
Storage conditions 10 mM Tris-HCl (pH 7.5); 200 mM NaCl; 0.1 mM EDTA; 7 mM 2-mercaptoethanol; 200 μg/ml BSA, and 50% glycerol; Store at -20°C.
Ligation After 2-fold overdigestion with enzyme approximately 90% of the DNA fragments can be ligated and recut.
Nonspecific hydrolysis No nonspecific activity was detected after incubation of 1 μg of Lambda DNA with 2 u.a. of enzyme for 16 hours at 55°C.
Methylation sensitivity not tested
Reagents supplied with enzyme 10 X SE-buffer Y
