Universal CG cloning of polymerase chain reaction products
Single-insert cloning of DNA fragments without restriction enzymes has traditionally been achieved using TA cloning, with annealing of a polymerase chain reaction (PCR) fragment containing a single overhanging 3′ A to a plasmid vector containing a 3′ T. In this article, we show that the analogous “C...

Summary: | Single-insert cloning of DNA fragments without restriction enzymes has traditionally been achieved using TA cloning, with annealing of a polymerase chain reaction (PCR) fragment containing a single overhanging 3′ A to a plasmid vector containing a 3′ T. In this article, we show that the analogous “CG cloning” is faster and far more efficient, using AhdI to generate a C-vector. For an afternoon ligation, CG cloning achieved double the cloning efficiency and more than 4-fold the number of transformants compared with TA cloning. However, blunt-end ligation was markedly more efficient than both. CG cloning could prove to be extremely useful for single-copy high-throughput cloning. |
