Recognition Site:
isoschizomers | compatible ends | single letter code
Source:
Flavobacterium aquatile NL3 (S.K. Degtyarev)
Reagents Supplied:
SEBuffer G
Enzyme Properties
Activity in NEBuffers:
| NEBuffer 1: | | 10% | | NEBuffer 2: | | 100% | | NEBuffer 3: | | 50% | | NEBuffer 4: | | 50% |
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 |
Activity at 37°C:
20%
Heat Inactivation:
65°C for 20 minutes
Survival in a Reaction:
Minimum units to digest 1 µg of substrate DNA in 16 hours: 0.25 unit(s)
Reaction & Storage Conditions
Reaction Conditions:

55°C.
1X SEBuffer G:
10 mM Tris-HCl
50 mM NaCl
10 mM MgCl2
1 mM Dithiothreitol
pH 7.6 @ 25°C
Unit Definition:
One unit is defined as the amount of enzyme required to digest 1 µg of pUC19 DNA in 1 hour at 55°C in a total reaction volume of 50 µl.
Unit Assay Substrate:
pUC19 DNA
Storage Conditions:
20 mM Tris-HCl
50 mM KCl
1 mM Dithiothreitol
0.1 mM EDTA
200 µg/ml BSA

Notes
General notes:- FatI is a neoschizomer of NlaIII.
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 3-fold overdigestion with FatI, > 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 FatI.
16-Hour Incubation:
A 50 μl reaction containing 1 μg of λDNA
and 2 units of FatI incubated for 16 hours at 55ºC
resulted in a DNA pattern free of detectable nuclease degradation as determined by agarose gel electrophoresis.
