The successful assembly of DNA can be utilized for both cloning and synthetic biology (in which genes and proteins are redesigned and/or assembled into novel ways to create new and useful functionality). New England Biolabs offers several products that can be used for DNA assembly and cloning of multiple DNA fragments, including NEB Gibson Assembly®, NEBuilder® HiFi DNA Assembly, which utilizes a higher fidelity polymerase, and Golden Gate Assembly. Please refer to the DNA Assembly Selection Chart to determine which product would work best for your needs.
PCR cloning is a rapid method for cloning genes, and is often used for projects that require higher throughput than traditional cloning methods can accommodate. It also allows for cloning of fragments that are not available in large amounts. NEB offers an affordable cloning kit as an alternative to TOPO®. The NEB PCR Cloning Kit allows quick and simple cloning of all your PCR amplicons, regardless of the polymerase used. This kit utilizes a novel mechanism for background colony suppression – a toxic minigene is generated when the vector closes upon itself – and allows for direct cloning from your PCR reaction with no purification step. The NEB PCR Cloning Kit is available with and without competent cells.
NEB offers the Q5 Site-Directed Mutagenesis Kit as an alternative to QuikChange™. The kit allows for rapid, site-specific mutagenesis of double-stranded plasmid DNA in less than 2 hours. The Q5 Site-Directed Mutagenesis Kit is available with and without competent cells.
