|Optimal SE-buffer||G (10 mM Tris-HCl (pH 7.6 at 25°C); 10 mM MgCl2; 50 mM NaCl; 1 mM DTT.) + BSA|
|Enzyme activity (%)|
|75 - 100||100||25 - 50||25 - 50||75 - 100||100|
|Storage conditions||10 mM Tris-HCl (pH 7.5); 200 mM NaCl; 0,1 mM EDTA; 1 mM DTT; 200 μg/ml BSA; 50% glycerol. Store at -20°C.|
|Ligation||After 10-fold overdigestion with enzyme 50% 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 G, BSA
For E481T and E482T an additional 10X SE-buffer ROSE is supplied.
|Methylation sensitivity||Blocked by overlapping
CG methylation: CCTmCG.|
|Inactivation 20 minutes under||65oC|
|Notes||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.
Turbo Mnl I can be used for short time (10 min) DNA digestion as well as for standard reaction. The reaction can be performed using optimal or universal (ROSE) Buffer
Turbo DNA Digestion:
-Fast DNA analysis
-Fast preparation of vectors for cloning
1 μl of Turbo Mnl I cuts 1 μg of DNA in 1 x SE-Buffer G or universal 1 x SE-Buffer ROSE in 10 min (see the protocol below). A short time of DNA digestion requires high quality purification of DNA sample. The enzyme may be used in standard conditions of DNA cleavage (E481).
Turbo reaction protocol:
20 μl of the reaction volume:
10 x SE Buffer ROSE - 2 μl
DNA - 0,2-1 μg
Nuclease-free water - to 20 μl
+ 1μl of Turbo Mnl I
Incubate at 37°C for 10 min.
