Twenty years ago, the TOPO name became synonymous with superior quality and game-changing innovation in PCR cloning. Today, Invitrogen TOPO cloning kits are still the fastest, simplest, and most efficient cloning solutions available. There is no substitute.
No matter what your downstream application is, TOPO PCR cloning solutions help you get the right clone sooner, freeing up your time to answer more important questions.
Eliminate blue/white screening with TOPO Zero Blunt vectors, which contain a lethal ccdB gene. When disrupted by the insertion of a PCR product, only positive recombinants are permitted to grow upon transformation.
Invitrogen TOPO PCR cloning technology was developed to help improve cloning efficiency, simplify protocol setup, and accommodate a wide range of PCR insert sizes. TOPO technology enables inserts with compatible ends to be readily joined to the vector in 5 minutes, without the need for additional ligation steps. Learn more about our TOPO cloning solutions below.
For the direct insertion of blunt-end PCR products amplified with proofreading thermostable polymerases into a plasmid vector. Now with 25% extra reactions.
For the direct insertion of Taq polymerase–amplified PCR products into a plasmid vector for subcloning. Now with 25% extra reactions.
For easy, highly efficient cloning of extra-long PCR products (up to 13kb) using the new linearized, topoisomerase I-activated pCR™-XL-2-TOPO vector.
Now with 25% extra reactions.
Learn how simple it is to get 95% recovery of your clone in just 5 minutes.
