Recognition Site:
isoschizomers | compatible ends | single letter code
Source:
Proteus vulgaris (ATCC 13315)
Reagents Supplied:
NEBuffer 3 (10X)
BSA (100X)
Enzyme Properties
Activity in NEBuffers:
| NEBuffer 1: | | 10% | | NEBuffer 2: | | 75% | | NEBuffer 3: | | 100% | | NEBuffer 4: | | 10% |
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: Blocked |
Heat Inactivation:
80°C for 20 minutes
Survival in a Reaction:
Minimum units to digest 1 µg of substrate DNA in 16 hours: 0.13 unit(s)
Reaction & Storage Conditions
Reaction Conditions:
1X NEBuffer 3
Supplemented with 100 μg/ml Bovine Serum Albumin

Concentration:
10,000 units/ml
Unit Assay Substrate:
λ DNA (HindIII digest)
Storage Conditions:
10 mM Tris-HCl
300 mM NaCl
1 mM Dithiothreitol

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 50-fold overdigestion with PvuI, > 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 PvuI.
16-Hour Incubation:
A 50 μl reaction containing 1 μg of DNA
and 50 units of PvuI 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 PvuI 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.
Endonuclease Activity:
Incubation of a 50 μl reaction containing 100 units of PvuI with 1 μg of
ΦX174 RF I DNA for 4 hours at 37ºC resulted
in < 10% conversion to RFII as determined by agarose gel electrophoresis.
