Zero Blunt® TOPO® PCR Cloning Kits offers the fastest and easiest method for high-efficiency (cloning of blunt-end PCR products amplified with proofreading thermostable polymerases. The kits include linearized and topoisomerase I-activated pCR®-Blunt II-TOPO® Vector for 5-minute benchtop ligations without ligase (1). The pCR®-Blunt II-TOPO® Vector also features:

• ccdB gene for positive selection (2)
• EcoR I 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

Selected Zero Blunt® TOPO® PCR Cloning Kits are available in combo kits combined with a PureLink™ Quick Plasmid Miniprep Kit (50 preps) for fast plasmid purification of your TOPO®-cloned inserts for downstream analysis.
