The pSTBlue-1 AccepTor™ Vector Giga Kits and pSTBlue-1 Perfectly Blunt® Giga Cloning Kits feature NovaBlue GigaSingles™ Competent Cells for increased transformation efficiency. AccepTor Vector Kits are designed for the cloning of PCR products generated using thermostable DNA polymerases that leave single 3′-dA nucleotide overhangs. The vector enables direct ligation by virtue of single 3′-dU overhangs that anneal with 3′-dA extensions on PCR products. The dU residues are converted to dT residues in vivo.

The Perfectly Blunt Cloning Kits are designed for the cloning of DNA generated by PCR using any type of DNA polymerase. This allows for the use of high-fidelity proofreading enzymes for amplification, thereby decreasing the probability of generating mutations in the target sequence.
