Unit definition One unit of the enzyme is the amount required to hydrolyze 1 μg of T7 DNA in 1 hour at 37°C in a total reaction volume of 50 μl.
Assayed on T7 DNA
Storage conditions 10 mM Tris-HCl (pH 7.5); 50 mM KCl; 0.1 mM EDTA; 7 mM 2-mercaptoethanol; 200 μg/ml BSA; 50% glycerol; Store at -20°C.
Ligation After 3-fold overdigestion with enzyme more than 80% of the DNA fragments can be ligated and recut.
Nonspecific hydrolysis No nonspecific activity was detected after incubation of 1 μg of T7 DNA with 2 u.a. of enzyme for 16 hours at 37°C.
Methylation sensitivity not tested
Reagents supplied with enzyme 10 X SE-buffer B
Notes High enzyme concentration may result in star activity.
