Does XhoI produce sticky ends?
These enzymes are made in bacteria to degrade viral DNA. Cutting DNA with restriction enzymes can produce fragments with either blunt or sticky ends. XhoI – recognises the sequence 5’CTCGAG’3 – sticky ends. HindIII – recognises the sequence 5’AAGCTT’3 – sticky ends.
What is the difference between blunt ends and sticky ends of DNA cut by restriction enzymes?
Answer: Blunt and sticky ends areresult of restriction endonuclease action on double stranded DNA. Sticky Ends – are staggered ends on a DNA molecule with short, single-stranded overhangs. Blunt Ends are a straight cut, down through the DNA that results in a flat pair of bases on the ends of the DNA.
Which restriction enzyme forms blunt ends?
Other restriction endonucleases produce “blunt end” in which there are no unpaired bases or overhangs in the end of the fragments. These pieces of DNA can not anneal to each other and hence are more difficult to clone.

Which is the high fidelity version of Spei?
SpeI has a High Fidelity version SpeI-HF ® ( NEB #R3133 ). 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.
What kind of quality control Does Neb use?
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.
What does Neb do for HF restriction enzymes?
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.
