TA Cloning® Kits are designed for cloning Taq-amplified PCR products directly from a PCR reaction using an overnight ligation step. The kits use a pCR™ vector and yield ≥80% recombinants with ≥90% of the recombinants containing inserts.

Some of the convenient features of the pCR™ vectors are:

• 3´-T overhangs for direct ligation of Taq-amplified PCR products
• Choice of T7 (pCR™2.1) or T7 and Sp6 (pCR™II) promoters for in vitro RNA transcription and sequencing
• Versatile polylinker with flanking EcoR I sites for easy excision of inserts
• Choice of kanamycin or ampicillin selection
• Easy blue/white colony screening
• M13 forward and reverse primer sites for sequencing
For Research Use Only. Not for use in diagnostic procedures.

Frequently asked questions (FAQs)

Can I use TOP10F' competent cells for transformation of my TOPO vector that contains the ccdB gene?

Strains that contain an F plasmid, such as TOP10F', are not recommended for transformation and selection of recombinant clones in any TOPO vector containing the ccdB gene. While the F plasmid does encode the CcdA protein, which acts as an inhibitor of the CcdB gyrase-toxin protein, the half-life of the CcdA protein is shorter than that of the CcdB protein. Overexpression of the CcdB protein causes cell death when its action is not prevented by sufficient CcdA.
