A E. coli strain that carries the AclI gene from Acinetobacter calcoaceticus M4 (S.K. Degtyarev).
Activity in NEBuffers:
NEBuffer 1: 10%
NEBuffer 2: 10%
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.
dam methylation: Not sensitive
dcm methylation: Not sensitive
CpG methylation: Blocked
More information about: Methylation Sensitivity
Survival in a Reaction:
(+) Intermediate activity. Suitable for extended digestion, but < 8 hours.
More information about: Extended Digests with Restriction Enzymes
Reaction & Storage Conditions
1X NEBuffer 4
Supplemented with 100 μg/ml Bovine Serum Albumin
Incubate at 37°C.
1X NEBuffer 4:
20 mM Tris-acetate
50 mM potassium acetate
10 mM Magnesium Acetate
1 mM Dithiothreitol
pH 7.9 @ 25°C
One unit is defined as the amount of enzyme required to digest 1 µg of λ DNA in 1 hour at 37°C in a total reaction volume of 50 µl.
Unit Assay Substrate:
10 mM Tris-HCl
100 mM KCl
1 mM Dithiothreitol
0.1 mM EDTA
200 µg/ml BSA
pH 7.4 @ 25°C
1. AclI is an isoschizomer of Psp1406I.
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 AclI, > 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 AclI.
A 50 μl reaction containing 1 μg of DNA and 30 units of AclI incubated for 16 hours at 37ºC resulted in a DNA pattern free of detectable nuclease degradation as determined by agarose gel electrophoresis.
Incubation of a 50 μl reaction containing 15 units of AclI 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.
