Unit definition One unit of the enzyme is the amount required to hydrolyze 1 μg of Lambda DNA (dam-) in 1 hour at 50°C in a total reaction volume of 50 μl.
Assayed on Lambda DNA (dam-)
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 20-fold overdigestion with enzyme more than 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 40 u.a. of enzyme for 16 hours at 50°C.
Methylation sensitivity Blocked by overlapping Dam methylation (G m ATC) TCCG GA TC and GA TC CGGA.
Reagents supplied with enzyme 10 X SE-buffer 2K
