Abstract
Blunt-end DNA fragments can be ligated into Promega's T-Vectors if they are first "tailed" using dATP and Taq DNA Polymerase. In this article, the results of two different A-tailing protocols were evaluated using a pGEM®-T Easy Vector System. A standard A-tailing protocol was compared to an abbreviated alternative protocol using both PCR products generated by thermostable DNA polymerases that have proofreading activity, and modified blunt-end DNA fragments generated by restriction digestion. The efficiency of cloning long PCR fragments into the pGEM®-T Vector Systems was also evaluated.
