Includes: Topoisomerase I-activated pCR™2.1-TOPO™ vector; PCR buffer; Salt solution; dNTPs; Control template; M13 forward and reverse primers; Control PCR primers; Sterile water; One Shot™ Chemically Competent or Electrocomp™ E. coli; S.O.C. medium; Supercoiled pUC19 control plasmid



Uses a pCR™-TOPO Vector with covalently bound topoisomerase I for fast cloning and recombinants.

  • 3'-T overhangs for direct ligation of Taq-amplified PCR products
  • Choice of T7 (pCR2.1-TOPO™) or T7 and SP6 (pCRII-TOPO™) promoters for in vitro RNA transcription and sequencing. Each vector also contains M13 forward and reverse primer sites for sequencing.
  • EcoR I sites flanking the PCR product insertion site for easy excision of inserts
  • Kanamycin and ampicillin resistance genes for your choice of selection in E. coli
  • Easy blue/white colony screening for selection of recombinants
  • TOPO TA 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
