Store at -20°C. Assayed on Lambda DNA Ligation After 20-fold overdigestion with enzyme about 90% of the DNA fragments can be ligated and recut. Non-specific activity No nonspecific activity was detected after incubation of 1 ug of DNA with 40 u.a. of enzyme for 16 hours at 55°C. Optimum temperature 55 oC Inactivation 20 minutes 80oC Optimum SE-buffer W (10 mM Tris-HCl (pH 8.5 at 25°C); 10 mM MgCl2; 100 mM NaCl; 1 mM DTT.) + BSA Enzyme % activity: B G O W Y 0 - 10 10 - 25 25 - 50 100 75 - 100 Note: Do not use BSA for long incubation To obtain 100% activity, BSA should be added to the 1 x reaction mix to a final concentration of 100 ug/ml.
