How does NEBuilder work?

NEBuilder HiFi DNA Assembly enables virtually error-free joining of DNA fragments, even those with 5´- and 3´-end mismatches. This flexible mix enables simple and fast seamless cloning utilizing a proprietary high-fidelity polymerase. Find out why NEBuilder HiFi is the next generation of DNA assembly and cloning.

What is HiFi cloning?

This method allows for seamless assembly of multiple DNA fragments, regardless of fragment length or end compatibility. This method has been used to assemble either single-stranded oligonucleotides or different sizes of DNA fragments with varied overlaps (15–30 bp).

How does Gibson work?

The Gibson Assembly® method is a cloning procedure that allows the cloning of two or more fragments without the need for restriction enzyme digestion or compatible restriction sites. Instead, user-defined overlapping ends are incorporated into the fragments to allow the seamless joining of adjacent fragments.

How is Gibson assembly scarless?

The entire Gibson assembly reaction requires few components with minor manipulations. The exonuclease chews back DNA from the 5′ end, thus not inhibiting polymerase activity and allowing the reaction to occur in one single process. The resulting single-stranded regions on adjacent DNA fragments can anneal.

Which enzymes are used in Gibson assembly?

Gibson Assembly employs three enzymatic activities in a single-tube reaction: 5´ exonuclease, the 3´ extension activity of a DNA polymerase and DNA ligase activity. The 5´ exonuclease activity chews back the 5´ end sequences and exposes the complementary sequence for annealing.

Is Golden Gate Assembly scarless?

Golden Gate Cloning or Golden Gate assembly is a molecular cloning method that allows a researcher to simultaneously and directionally assemble multiple DNA fragments into a single piece using Type IIS restriction enzymes and T4 DNA ligase. In practice, this means that Golden Gate Cloning is typically scarless.

Which enzymes are used in Golden Gate Assembly?

Golden Gate assembly utilizes a Type IIS restriction enzyme (REase), which cleaves outside of its non-palindromic recognition sequence and T4 DNA Ligase in a simultaneous, single-tube reaction.

How is PCR used in site-directed mutagenesis?

Traditional PCR When PCR is used for site-directed mutagenesis, the primers are designed to include the desired change, which could be base substitution, addition, or deletion (Figure 1). During PCR, the mutation is incorporated into the amplicon, replacing the original sequence.
