|75 - 100||50 - 75||0 - 10||0 - 10||100||25|
|Storage conditions||10 mM Tris-HCl (pH 7.5); 250 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 20 u.a. of enzyme for 16 hours at 37°C
|Reagents Supplied with Enzyme||
10 X SE-buffer Y, BSA|
|Methylation sensitivity||not tested|
|Inactivation 20 minutes under||65oC|
|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.
