The cloning strategy is based on in vivo recombination of the linear vector and insert DNA fragment containing common flanking sequences. The recombination-mediated approach enables directional cloning of any PCR products into the vector without the need for restriction enzyme digestion or ligation reactions. Inserts designed for cloning into pTrham linearized vectors are generated by PCR with primers having 15 to 20 bases of homology with the ends of the vector. The PCR product is mixed with the corresponding cloning-ready vector and transformed into competent E. coli cells. No further enzymatic step after PCR amplification or purification of the vector and inserts are required. At least two PCR fragments can be assembled simultaneously into a vector with a high efficiency. Compared with the conventional restriction-ligation-dependent or other ligase-independent cloning approaches, the recombinational cloning is simplest and fastest method available. In addition to simplicity, the system is very robust and highly efficient.
