Description

Includes the Zero Blunt TOPO vector containing the ccdB gene for positive selection, only permitting growth of plasmid vectors with recombinants. Resistant to Kanamycin (KanR) and Zeocin™ (ZeoR).
pCRBlunt II-TOPO vector: designed for proofreading polymerases
The pCRBlunt II-TOPO vector is designed to clone blunt-ended PCR products generated by thermostable proofreading polymerases such as Platinum™ Pfx DNA Polymerase. The pCRBlunt II-TOPO vector contains:

• EcoRI sites flanking the PCR product insertion site for easy excision of inserts
• Kanamycin and Zeocin resistance genes for your choice of selection in E. coli
• SP6 promoter/primer site for in vitro RNA transcription and sequencing
• M13 forward and reverse primer sites for sequencing or PCR screening

pCRBlunt II-TOPO clone selection
pCRBlunt II-TOPO allows for direct selection of recombinants via disruption of the lethal E. coli gene, ccdB. The vector contains the ccdB gene fused to the C-terminus of the LacZα fragment. Ligation of a blunt-end PCR product disrupts expression of the LacZα-ccdB gene fusion, permitting growth of only positive recombinants upon transformation. Cells that contain non-recombinant vector are killed upon plating. Therefore, blue/white screening is not required.
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 E. coli competent cells.
Efficient cloning
With up to 95% of clones carrying the desired insert, you can screen fewer clones, saving you time and money. The pCRBlunt II-TOPO vector used in this kit comes with lethal ccdB gene for efficient selection of blunt-ended PCR recombinants products generated by thermostable proofreading polymerases.
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.
