DraIII-HF®

Dra-III-cutsite_1

Isoschizomers | Single Letter Code | Pronunciation:

High-Fidelity (HF^®) restriction enzymes have the same specificity as native enzymes, but have been engineered for significantly reduced star activity and performance in a single buffer (CutSmart^® Buffer). All HF-restriction enzymes come with Gel Loading Dye, Purple (6X). Enjoy the enhanced performance and added value of our engineered enzymes at the same price as the native enzyme:

Engineered for improved performance
100% activity in CutSmart Buffer
Time-Saver™ qualified for digestion in 5-15 minutes
Reduced star activity
Supplied with 1 vial of Gel Loading Dye, Purple (6X)

Product Information
High Fidelity (HF) Restriction Enzymes have 100% activity in CutSmart Buffer; single-buffer simplicity means more straightforward and streamlined sample processing. HF enzymes also exhibit dramatically reduced star activity. HF enzymes are all Time-Saver qualified and can therefore cut substrate DNA in 5-15 with the flexibility to digest overnight without degradation to DNA. Engineered with performance in mind, HF restriction enzymes are fully active under a broader range of conditions, minimizing off-target products, while offering flexibility in experimental design.

NEB extensively performs quality controls on all standard and high-fidelity (HF) restriction enzymes. Examples of nuclease contamination studies for some of our HF restriction enzymes are shown below.

Restriction Enzyme Competitor Study: Nuclease Contamination

EcoRI, NotI, and BamHI from multiple suppliers were tested in reactions containing a fluorescent labeled single stranded, double stranded blunt, 3’overhang or 5’ overhang containing oligonucleotides. The percent degradation is determined by capillary electrophoresis and peak analysis. The resolution is at the single nucleotide level.

Product Source
An E. coli strain that carries the cloned and modified DraIII gene from Deinococcus radiophilus (ATCC 27603).

  What does HF® refer to following the name of a restriction enzyme?
  
  Do I have to set-up digests with Time-Saver™ qualified enzymes for 5-15 minutes? Can I digest longer?
  
  I tested your restriction enzyme on the substrate DNA recommended by NEB, and it appears to be active, however it does not digest my DNA. What could be the reason?
  
  Is Gel Loading Dye, Purple (6X) or Gel Loading Dye, Purple (6X), no SDS compatible with other DNA binding dyes such as SYBR® and GelRed™ during gel electrophoresis?
  
  Can Gel Loading Dye, Purple 6X (B7024) be stored in cold temperatures?
  
  Why is my Restriction Enzyme not cutting DNA?
  
  Why do I see additional DNA bands on my gel after a restriction digest?
