What does HindIII restriction enzyme do?
HindIII (pronounced “Hin D Three”) is a type II site-specific deoxyribonuclease restriction enzyme isolated from Haemophilus influenzae that cleaves the DNA palindromic sequence AAGCTT in the presence of the cofactor Mg2+ via hydrolysis.
What is EcoRI digest?
EcoRI (pronounced “eco R one”) is a restriction endonuclease enzyme isolated from species E. coli. It is a restriction enzyme that cleaves DNA double helices into fragments at specific sites, and is also a part of the restriction modification system.
Which enzyme is used in restriction digestion?
Restriction Endonucleases
What is Restriction Digestion? Restriction Digestion is the process of cutting DNA molecules into smaller pieces with special enzymes called Restriction Endonucleases (sometimes just called Restriction Enzymes or RE’s).
Why is HindIII used instead of EcoRI?
EcoRI is a type II restriction enzyme that is isolated from E. coli species, while HindIII is a type II restriction enzyme that is isolated from Haemophilus influenza species. Thus, this is the key difference between EcoRI and HindIII.
Is HindIII sensitive to methylation?
Restriction Enzyme HincII Is Sensitive to Methylation of Cytosine That Occurs 5′ to the Recognition Sequence.
Why is BSA added to restriction digest?
Adding BSA to a reaction lessens enzyme loss on tube and pipette tip surfaces. BSA stabilizes enzymes in reaction. The stabilizing effects are most pronounced in overnight reactions (Robinson D.
What are the benefits of restriction digestion by endonuclease?
restriction enzyme, also called restriction endonuclease, a protein produced by bacteria that cleaves DNA at specific sites along the molecule. In the bacterial cell, restriction enzymes cleave foreign DNA, thus eliminating infecting organisms.
Is pbr322 a restriction enzyme?
It contains the origin of replication of pMB1, and the rop gene, which encodes a restrictor of plasmid copy number. The plasmid has unique restriction sites for more than forty restriction enzymes.
How many enzymes are used in restriction digest?
An analytical-scale restriction enzyme digestion is usually performed in a volume of 20μl with 0.2–1.5μg of substrate DNA and a two- to tenfold excess of enzyme. If an unusually large volume of DNA or enzyme is used, aberrant results may occur. The following protocol is an example of a typical RE digestion.
Can I use Thermo Scientific restriction enzymes in double digestion?
For optimal results with fast reaction and 100% buffer compatibility, we highly recommend using FastDigest restriction enzymes in double digestion. In certain cases however, it may be possible to perform double digestion using a mix of Thermo Scientific conventional and Fastdigest restriction enzymes.
What is the best restriction enzyme for DNA digestion?
Note: Also available as a FastDigest enzyme for rapid DNA digestion. Thermo Scientific conventional restriction endonucleases are a large collection of high quality restriction enzymes, optimized to work in one of the buffers of the Five Buffer System. In addition, the universal Tango buffer is provided for convenience in double digestions.
What is Thermo Scientific FastDigest PvuII restriction enzyme?
Thermo Scientific FastDigest PvuII restriction enzyme recognizes CAG^CTG site and cuts best at 37°C in 5–15 minutes using universal FastDigest Buffer. Thermo Scientific FastDigest PvuII is one of an advanced line of fast restriction enzymes that are all 100% active in the universal FastDigest and FastDigest Green reaction buffers.
Why 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. An E.coli strain that carries the PvuII gene from Proteus vulgaris (ATCC 13315). The following reagents are supplied with this product:
