Unit definitionOne 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-bufferO (50 mM Tris-HCl (pH 7.6 at 25°C); 10 mM MgCl2; 100 mM NaCl; 1 mM DTT.)
Enzyme activity (%)
BGOWYRose
10 - 2525 - 5010075 - 10010 - 2580
Optimal temperature
37oC
Storage conditions10 mM Tris-HCl (pH 7.5); 100 mM NaCl; 0.1 mM EDTA; 7 mM 2-mercaptoethanol; 100 μg/ml BSA; 50% glycerol. Store at -20°C.
LigationAfter 10-fold overdigestion with enzyme more than 90% of the DNA fragments can be ligated and recut.
Non-specific hydrolisisNo 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 O
For E029T and E030T an additional 10X SE-buffer ROSE is supplied.
Methylation sensitivityCleaved of DNA is impaired by overlapping dcm-methylation (CmCWGG): GGWCCWGG.
Inactivation 20 minutes under
65oC
NotesTurbo Bme18 I can be used for short time (15 min) DNA digestion as well as for standard reaction.The reaction can be performed using optimal or universal (ROSE) Buffer.
Turbo DNA Digestion:
Applications:
-Fast DNA analysis
-Fast preparation of vectors for cloning
-Double digestion
Enzyme Properties: 1 μl of Turbo Bme18 I cuts 1 μg of DNA in 1 x SE-Buffer O or universal 1 x SE-Buffer ROSE in 15 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 (E029).
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 Bme18 I
Incubate at 37°C for 15 min.
