Recognition Site:
isoschizomers | compatible ends | single letter code
Source:
An E. coli strain that carries the cloned BciVI gene from Bacillus circulans (T. Le)
Reagents Supplied:
NEBuffer 4 (10X)
Enzyme Properties
Activity in NEBuffers:
| NEBuffer 1: | | 100% | | NEBuffer 2: | | 50% | | NEBuffer 3: | | 0% | | NEBuffer 4: | | 100% |
When using a buffer other than the optimal (supplied) NEBuffer, it may be necessary to add more enzyme to achieve complete digestion.
Methylation Sensitivity:
| dam methylation: Not sensitive | | dcm methylation: Not sensitive | | CpG methylation: Not sensitive |

Notes
General notes:- BciVI produces DNA fragments that have a single-base 3´ extension which are more difficult to ligate than blunt-ended fragments.
- Ligation was achieved using 2X Quick Ligation Kit (NEB #M2200), which contains 15% Polyethylene glycol (PEG 6000).
FAQs
- Is BciVI inhibited by salt?
- Can the DNA be ligated?
- Is the recognition site nonpalindromic?
- Is extended digestion of BciVI recommended?
Quality Control for Current Lot
Quality control values for a specific lot can be found on the datacard which accompanies each product.
Ligation and Re-cutting:
After a 10-fold overdigestion with BciVI, > 95%
of the DNA fragments can be ligated with T4 DNA Ligase (at a 5' termini concentration of 1-2 μM)
at 16ºC. Of these ligated fragments, > 95% can be recut with BciVI.
16-Hour Incubation:
A 50 μl reaction containing 1 μg of DNA
and 30 units of BciVI incubated for 16 hours at 37ºC
resulted in a DNA pattern free of detectable nuclease degradation as determined by agarose gel electrophoresis.
Exonuclease Activity:
Incubation of a 50 μl reaction containing 10 units of BciVI with 1 μg of a mixture of single and double-stranded
[3H] E. coli DNA (205 cpm/μg) for 4 hours at 37ºC
released < 0.2% of the total radioactivity.
