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.

5 Reasons to choose NEBuilder HiFi 

1. Save time – Enjoy simple and fast seamless cloning in as little as 15 minutes.
2. Flexibility – Use one system for both "standard-size" cloning and larger gene assembly products, up to 6 fragments.
3. Compatible with downstream applications – DNA can be used immediately for transformation or as template for PCR or RCA.
4. Adaptable – Adapts easily for multiple DNA manipulations, including site-directed mutagenesis. 
5. Save money - No licensing fees from NEB for NEBuilder products

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
