| Source | An E.coli strain, that carries the cloned gene BamHI from Bacillus amyloliquefaciens H |
| 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 | G (10 mM Tris-HCl (pH 7.6 at 25°C); 10 mM MgCl2; 50 mM NaCl; 1 mM DTT.) + BSA |
| Enzyme activity (%) | | B | G | O | W | Y | Rose | | 25 - 50 | 100 | 75 - 100 | 75 - 100 | 25 - 50 | 100 |
|
| Optimal temperature | 37oC |
| Storage conditions | 10 mM Tris-HCl (pH 7.6); 50 mM NaCl; 0,1 mM EDTA; 100 μg/ml BSA; 1 mM DTT; 50% glycerol. Store at -20°C. |
| Ligation | After 50-fold overdigestion with enzyme approximately 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 G, BSA (except E021T and E022T).
For E021T and E022T an additional 10X SE-buffer ROSE is supplied.
|
| Methylation sensitivity | Not blocked by Dam methylation (GmATC) GGATCC |
| Inactivation 20 minutes under | 65oC |
| Notes | High enzyme concentration may result in star activity.
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.
Turbo BamH 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:
Applications:
-Fast DNA analysis
-Fast preparation of vectors for cloning
-Double digestion
Enzyme Properties:
1 μl of Turbo BamH 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 (E021).
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 BamH I
Incubate at 37°C for 10 min.
