[Construction of a fused fpg gene by using TP-PCR method]

TP-PCR,a method developed for fusion gene construction without the use of endonuclease and ligase, was performed to construct a fused fpg gene. The TP-PCR reaction system contained three primers and two templates and resulting PCR product, fused fpg gene, consisted of three sections: pheB gene, which was responsible for catechol 2,3-dioxygenase, gfp gene for GFP protein and the intermediate ligation segment which was designed for the correct expression of the fusion gene. The result in this paper showed that the TP-PCR method is one of rapid and convenient methods for fused gene construction.
