Quality Control AssaysThe following Quality Control Tests are performed on each new lot and meet the specifications designated for the product. Individual lot data can be found on the Product Summary Sheet/Datacard or Manual which can be found in the Supporting Documents section of this page. Further information regarding NEB product quality can be found here.
- Exonuclease Activity (Radioactivity Release):
The product is tested in a reaction containing a radiolabeled mixture of single and double-stranded DNA. After incubation for 4 hours the exonuclease activity is determined by the % release of radioactive nucleotides.
- Ligation and Recutting (Terminal Integrity):
After an over-digestion of DNA with a restriction endonuclease the percentage of the DNA fragments ligated with T4 DNA ligase and the percentage that can be recut are determined by agarose gel electrophoresis.
- Non-Specific DNase Activity (16 hour):
The product is tested for non-specific nuclease degradation in a reaction containing a DNA substrate. After incubation for 16 hours there is no detectable degradation of the DNA substrate as determined by agarose gel electrophoresis.

- FatI is a neoschizomer of NlaIII.
- How many base pairs should be added at the end of a PCR primer after the FatI recognition site to guarantee that FatI will cut properly?
- Does FatI have any neoschizomers?
- What is the activity of FatI at 37°C?
- What effect does BSA have on the performance of NEB’s restriction enzymes when included in the new buffers?
- How can I access the old NEBuffer Activity Chart?
- What effect does BSA have on the performance of NEB's restriction enzymes when included in the new buffers?
- Why is my Restriction Enzyme not cutting DNA?
- Why do I see a DNA smear on an agarose gel after a restriction digest?
- Why do I see additional DNA bands on my gel after a restriction digest?
- How many nucleotides do I have to add adjacent to the RE recognition site in order to get efficient cutting?
