Abstract
Methods to fuse multiple DNA fragments are extremely useful in synthetic biology and protein engineering. Here, we report a gold nanoparticle-mediated simultaneous overlap extension-PCR (AuNP-mediated SOE-PCR) method that enables the fusion of multiple DNA fragments simultaneously with their amplification in a single reaction using typical PCR conditions. Using greater concentrations of rTaq DNA polymerase and AuNPs significantly improves the performance of SOE-PCR especially for the fusion of more than three DNA fragments. We show that up to six lambda DNA fragments can be simultaneously fused by AuNP-mediated SOE-PCR.
