Unit definition One unit of the enzyme is the amount required to hydrolyze 1 μg of Lambda DNA/HindIII in 1 hour at 37°C in a total reaction volume of 50 μl.
Assayed on Lambda DNA/HindIII
Storage conditions 10 mM Tris-HCl (pH 7.5); 200 mM NaCl; 0.1 mM EDTA; 7 mM 2-mercaptoethanol; 200 μg/ml BSA; 50% glycerol. Store at -20°C.
Ligation After 5-fold overdigestion with enzyme more than 70% of the DNA fragments can be ligated and more than 80% of these can be recut.
Nonspecific hydrolysis No nonspecific activity was detected after incubation of 1 μg of Lambda DNA with 5 u.a. of enzyme for 16 hours at 37°C.
Methylation sensitivity Blocked by overlapping Dcm methylation(C m CWGG) RGGW CCT GG.
Supplied with enzyme 10 X SE-buffer Y, BSA
Notes To obtain 100% activity, BSA should be added to the 1x reaction mix to a final concentration of 100 μg/ml. Do not use BSA for long incubation.
