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); 50 mM KCl; 0.1 mM EDTA; 7 mM 2-mercaptoethanol; 200 μg/ml BSA; 50% glycerol; Store at -20°C.
Ligation After 10-fold overdigestion with enzyme more than 95% 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 20 u.a. of enzyme for 16 hours at 55°C.
Methylation sensitivity Blocked by GC methylation: 5`-G(5mC)NNGC-3`/3`-CGNN(5mC)G-5`.
Reagents supplied with enzyme 10 X SE-buffer Y
Notes At 37°C activity is 50% from maximum.
