Assayed onLambda DNA
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-bufferB (10 mM Tris-HCl (pH 7.6 at 25°C); 10 mM MgCl2; 1 mM DTT.) + BSA
Enzyme activity (%)
BGOWYRose
10025 - 5025 - 5025 - 5075 - 10050
Optimal temperature
37oC
Storage conditions10 mM Tris-HCl(pH 7.5); 50 mM NaCl; 0,1 mM EDTA; 1 mM DTT; 200 μg/ml BSA; 50% glycerol; Store at -20°C.
LigationAfter 20-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 B, BSA
For E079T and E080T an additional 10X SE-buffer ROSE+ is supplied.
Methylation sensitivityNot blocked by overlapping Dcm methylation (CmCWGG): GGTACCWGG
Inactivation 20 minutes under
80oC
NotesHigh enzyme concentration may result in star activity.
Long incubation with BSA is not recommended due to star activity.
To obtain 100% activity, BSA should be added to the 1 x reaction mix to a final concentration of 100 μg/ml.
Turbo Kpn 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 Kpn I cuts 1 μg of DNA in 1 x SE-Buffer B with BSA 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 (E079).
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 Kpn I
Incubate at 37°C for 15 min.
