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
Storage conditions 10 mM Tris-HCl (pH 7.5); 50 mM KCl; 0.1 mM EDTA; 7 mM 2-mercaptoethanol; 200 μg/ml BSA; and 50% glycerol. Storage temperature: -20°C. Storage at -70°C is recommended for periods longer than 30 days.
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 37°C.
Methylation sensitivity not tested
Reagents supplied with enzyme 10 X SE-buffer B, BSA
Notes To obtain 100% activity, BSA should be added to the 1 x reaction mix to a final concentration of 100 μg/ml. Do not use BSA for long incubation.
