A E. coli strain that carries the BanI gene from Bacillus aneurinolyticus (IAM 1077).
Reagents Supplied:
NEBuffer 4
BSA
Enzyme Properties
Activity in NEBuffers:
| NEBuffer 1: | | 50% | | NEBuffer 2: | | 100% | | NEBuffer 3: | | 50% | | 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: Blocked by some combinations of overlapping | | CpG methylation: Blocked by some combinations of overlapping | |
More information about: Methylation Sensitivity |
Heat Inactivation:
65°C for 20 minutes
Survival in a Reaction:
(+ + +) Suitable for an extended or overnight digestion. Enzyme is active > 8 hours.

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 BanI, > 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 BanI.
16-Hour Incubation:
A 50 μl reaction containing 1 μg of DNA
and 20 units of BanI 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 100 units of BanI with 1 μg of a mixture of single and double-stranded
[3H] E. coli DNA (205 cpm/μg) for 4 hours at 37ºC
released < 0.1% of the total radioactivity.
