Enzyme activity (%)
25 - 5050 - 7510 - 2510 - 2575 - 100100
Optimal temperature
Storage conditions10 mM Tris-HCl (pH 7.5); 50 mM KCl; 0,1 mM EDTA; 7 mM 2-mercaptoethanol; 200 μg/ml BSA; 50% glycerol; Store at -20°C.
LigationsAfter 2-fold overdigestion with enzyme more then 90% of the DNA fragments can be ligated with T4 DNA Ligase at 16°C and recut.
Non-specific hydrolisisNo nonspecific activity was detected after incubation of 1 μg of pUC19 DNA with 1 u.a. of enzyme for 16 hours at 37°C.
Reagents Supplied with Enzyme 10 X SE-buffer FaeI, BSA
Methylation sensitivityBlocked by CmATG methylation
Inactivation 20 minutes under
NotesTo obtain 100% activity, BSA should be added the 1x reaction mix to a final concentration of 100 μg/ml.
Do not use BSA for long incubation.
