Invitrogen™ Zero Blunt™ TOPO™ PCR Cloning Kit for Sequencing, with One Shot™ TOP10 Chemically Competent E. coli 

Description

Each kit uses the pCR™4Blunt-TOPO vector with specially designed sequencing primer sites that return more insert sequence and less vector sequence from each reaction. Kits includes everything necessary to clone and select recombinant vectors containing your PCR fragment of choice.
pCR4Blunt-TOPO vector: optimized for sequencing
We have removed much of the multiple cloning site from the pCR4Blunt-TOPO vector to shorten the distance between sequencing primer sites and the insert site to as little as 33 bp. This means sequencing reactions give less vector sequence and more insert sequence. The pCR4Blunt TOPO vector has sites for four common sequencing primers: M13 forward, M13 reverse, T7, and T3. The kits include an aliquot of each.
pCR4Blunt-TOPO clone selection and manipulation
The pCR4Blunt-TOPO vector contains both ampicillin and kanamycin resistance markers and a LacZα-ccdB gene fusion for positive selection and blue/white screening. The vector's minimized multiple cloning site still includes flanking EcoRI sites for simplified excision of cloned PCR products and a unique Sse8387I site for generation of nested deletions prior to sequencing. T7 and T3 promoters are also present for in vitro transcription.
Simplified, TOPO-based cloning
Using TOPO cloning technology, there is no need for PCR primers containing specific sequences, post-PCR procedures, vector preparation, or other time-intensive DNA manipulation steps. Just add your PCR reaction straight to the provided topoisomerase-charged vector, incubate 5 minutes, and transform the provided E. coli competent cells.
Efficient cloning
With up to 95% of clones carrying the desired insert, you can screen fewer clones, which saves you time and money. The pCR4Blunt-TOPO vector used in this kit comes with no overhangs for efficient ligation of PCR products created by proofreading, thermostable polymerases that leave blunt-ended PCR products.
The standard in cloning
When it comes to cloning, TOPO cloning technology has been a reliable partner for thousands of scientists for over ten years. Fast, simple-to-use, and efficient, TOPO cloning has been applied to many different vectors for a wide array of applications.
