|Optimal SE-buffer||B (10 mM Tris-HCl (pH 7.6 at 25°C); 10 mM MgCl2; 1 mM DTT.)|
|Enzyme activity (%)|
|100||50 - 75||10 - 25||10 - 25||75 - 100||100|
|Storage conditions||10 mM Tris-HCl (pH 7.5); 100 mM NaCl; 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 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 B
For E127T and E128T an additional 10X SE-buffer ROSE is supplied.
|Methylation sensitivity||not tested|
|Inactivation 20 minutes under||65oC|
|Notes||Turbo Sfr303 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 Sfr303 I cuts 1 μg of DNA in 1 x SE-Buffer B 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 (E127).
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 Sfr303s I
Incubate at 37°C for 10 min.
