NEBuilder HiFi DNA Assembly enables virtually error-free joining of DNA fragments, even those with 5´- and 3´-end mismatches. This flexible kit 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.
4 Reasons to choose NEBuilder HiFi
- Save time – Enjoy simple and fast seamless cloning in as little as 15 minutes.
- Flexibility – Use one system for both "standard-size" cloning and larger gene assembly products, up to 6 fragments.
- Compatible with downstream applications – DNA can be used immediately for transformation or as template for PCR or RCA.
- Adaptable – Adapts easily for multiple DNA manipulations, including site-directed mutagenesis.
NEBuilder HiFi DNA assembly offers unique features over other DNA assembly methods, including:
- 3´- and 5´-end mismatch removal
- Bridging of two ds-fragments with a ssDNA oligo
- Improved methods for site-directed mutagenesis
