|Source||Acinetobacter calcoaceticus B1|
|Assayed on||Lambda DNA|
|Unit definition||One unit of the enzyme is the amount required to hydrolyze 1 μg of Lambda DNA in 1 hour at 37°C in a total reaction volume of 50 μl.|
|Optimal SE-buffer||K (10 mM Tris-HCl (pH 7.6 at 25°C); 10 mM MgCl2; 100 mM KCl; 1 mM DTT.) + BSA|
|Enzyme activity (%)|
|50 - 75||10 - 25||10 - 25||75 - 100||50 - 75||30|
|Storage conditions||10 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.
|Ligation||After 10-fold overdigestion with enzyme 95% 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 10 u.a. of enzyme for 16 hours at 37°C.
|Reagents Supplied with Enzyme||
10 X SE-buffer K, BSA|
|Methylation sensitivity||not tested|
|Inactivation 20 minutes under||65oC|
|Notes||High enzyme concentration may result in star activity|
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.
