Optimal SE-buffer B (10 mM Tris-HCl (pH 7.6 at 25°C); 10 mM MgCl2; 1 mM DTT.) Enzyme activity (%) B G O W Y Rose 100 50 - 75 0 - 10 50 - 75 75 - 100 50 Optimal temperature 37oC Storage conditions 10 mM Tris-HCl (pH 7.5); 100 mM NaCl; 0,1 mM EDTA; 7 mM 2-mercaptoethanol; 100 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. Non-specific hydrolisis 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.
