|Source||Bacillus stearothermophilus 6|
|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 65°C in a total reaction volume of 50 μl.|
|Optimal SE-buffer||Y (33 mM Tris-acetate (pH 7.9 at 25°C); 10 mM magnesium acetate; 66 mM potassium acetate; 1 mM DTT.) + BSA|
|Enzyme activity (%)|
|75 - 100||75 - 100||50 - 75||75 - 100||100||100|
|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. |
Storage at -20°C.
Storage at -70°C is recommended for periods longer than 30 days..
|Ligation||After 2-fold overdigestion with enzyme 80% of DNA fragments can be ligated. Of these 80% can be recut.|
|Non-specific hydrolisis||No nonspecific activity was detected after incubation of 1 μg of Lambda DNA with 5 u.a. of enzyme for 16 hours at 65°C.
|Reagents Supplied with Enzyme||
10 X SE-buffer Y, BSA|
|Methylation sensitivity||not tested|
|Inactivation 20 minutes under||80oC|
|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.
