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 NaCl; 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 20 u.a. of enzyme for 16 hours at 37°C.
Methylation sensitivity Blocked by CG methylation 5'-G(5mC)GC-3'/3'-CG(5mC)G-5'. Not blocked by methylation 5'-GCG(5mC)-3'/3'-CGCG-5'. Cut hemimethylated site:5'- G(5mC)GC-3'/3'-CGCG-5`
Supplied with enzyme 10 X SE-buffer Y
