|Source||An E.coli strain that carries the cloned FauND I gene from Flavobacterium aquatili ND|
|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||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 (%)|
|50 - 75||75 - 100||10 - 25||50 - 75||100||100|
|Storage conditions||10 mM Tris-HCl (pH 7.5); 50 mM KCl; 0,1 mM EDTA; 1mM DTT; 200 μg/ml BSA, 50% glycerol; Store at -20°C.|
|Ligation||After 10-fold overdigestion with enzyme 80% of the DNA fragments can be ligated and recut. In the presence of 10% PEG ligation is better.|
|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 Y, BSA
|Methylation sensitivity||not tested|
|Inactivation 20 minutes under||65oC|
|Notes||Sensitive to impurities present in some DNA preparations. For example, DNA purified by standard miniprep procedures is cleaved at lower rates.|
To obtain 100% activity, BSA should be added to the 1 x reaction mix to a final concentration of 100 μg/ml.
Do not use BSA for long incubation.
