The pCR™8/GW/TOPO® TA Cloning Kit delivers simple 5 minute cloning and access to the Gateway® recombination cloning vector platform. Our pCR™8 TOPO® TA vector contains a minimal MCS, so you sequence more of your insert and less of the vector.

With our patented att sites, the pCR™8 vector is the simplest way to create an Entry Clone, which facilitates easy access via Gateway® recombination cloning to a variety of expression vectors without tedious sub-cloning, saving you valuable research time.

The pCR™8/GW/TOPO® TA Cloning Kit offers:

att sites for rapid recombination into a variety of Gateway® destination vectors
• 3´-T overhangs for direct ligation of Taq-amplified PCR products
• Sequencing primer sites within 55 bp of insertion site ensures you sequence more insert, less vector
• Spectinomycin resistance gene for robust selection in E. coli
• EcoRI sites flanking the PCR product insertion site for easy excision of inserts

This kit includes One Shot® TOP10 Chemically Competent E. coli.
For Research Use Only. Not for use in diagnostic procedures.
