DescriptionTurbo AccB7 I is used for a short time (10 min) of 1 μg DNA digestion in universal (ROSE) SE-Buffer in 50 μl of reaction mixture.
Reaction Original SibEnzyme (ROSE) Buffer is a specially designed universal reaction buffer for the most Restriction Endonucleases. ROSE Buffer is perfect for DNA cleavage with SE Turbo Restriction Endonucleases and for double digestion.
Applications:
- Fast DNA analysis
- Fast preparation of vectors for cloning
- Double digestion
Reaction bufferSE-buffer ROSE
Optimal temperature
37oC
Storage conditions10 mM Tris-HCl (pH 7.5); 50 mM KCl; 0.1 mM EDTA; 7 mM 2-mercaptoethanol; 200 μg/ml BSA; 50% glycerol; Store at -20°C.
LigationAfter digestion with 1 μl of Turbo AccB7 I, approximately 95% of the DNA fragments can be ligated with high-activity T4 DNA Ligase and recut.
Non-specific hydrolisisNo detectable degradation of a single-stranded and double-stranded oligonucleotide was observed after incubation with 1 μl of restriction endonuclease for 3 hours.
Reagents Supplied with Enzyme 10 X SE-buffer ROSE
Methylation sensitivityBlocked by overlapping Dcm methylation (CmCWGG): CCANNNCCTGG or CCAGGNNNTGG.
Inactivation 20 minutes under
65oC
NotesEnzyme Properties:
1 μl of Turbo AccB7 I cuts 1 μg of DNA in 1x SE-Buffer ROSE in 10 min (assayed on Lambda DNA(dcm-) and plasmid DNA(dcm-)). A short time of DNA digestion requires high quality purification of DNA sample (PCR fragments should be purified after amplification).
Please note that supercoiled plasmid DNA and PCR fragments may have varying rates of cleavage and sometimes need more time to be completely digested.
Standard protocol of Turbo reaction:
20 μl of the reaction volume:
10x SE-Buffer ROSE - 2 μl
DNA - 0.2-1 μg
Nuclease-free water - to 20 μl
+ 1 μl of Turbo AccB7 I
Mix by pipette tip carefully.
Incubate at 37°C for 10 min.
