For applications such as sequencing, transfection, and in vitro transcription, PCR products have to be subcloned into plasmids. Many strategies are used for cloning, blunt-end ligation or the incorporation of restriction endonuclease sites into PCR primers for appropriate vectors. However, the most convenient and direct method is T/A cloning. In this study, we developed two of the pGEM-7Zf(+) phagemid T-tail vectors using AhdI-restriction endonuclease sites, and these T vectors have all the features of pGEM-7Zf(+): f1 ori, T7, and SP6 RNA polymerase promoters, the alpha-peptide coding region of beta-galactosidase for X-gal blue/white color selection, the beta-lactamase gene for recombinant colony selection, and binding sites for pUC/M13 forward and reverse sequencing primers. These AhdI-containing phagemid vectors, pGEM-NJ105 and pGEM-NJ107, are useful for the easy and inexpensive preparation of T vectors and direct cloning of PCR products.
