Optimal SE-buffer Y (33 mM Tris-acetate (pH 7.9 at 25°C); 10 mM magnesium acetate; 66 mM potassium acetate; 1 mM DTT.) Enzyme activity (%) B G O W Y R 50 - 75 75 - 100 10 - 25 25 - 50 100 100 Optimal temperature 37oC Storage conditions 10 mM Tris-HCl (pH 7.5); 100 mM NaCl; 0.1 mM EDTA; 7 mM 2-mercaptoethanol; 50% glycerol; Store at -20°C. Ligations After 2-fold overdigestion with enzyme about 5% of the DNA fragments can be ligated and recut. Non-specific hydrolisis No nonspecific activity was detected after incubation of 1 μg of Lambda DNA with 4 u.a. of enzyme for 16 hours at 37°C.
