Simple and efficient modification of Golden Gate design standards and parts using oligo stitching

The assembly of DNA parts is a critical aspect of contemporary biological research. Gibson assembly and Golden Gate cloning are two popular options. Here, we explore the use of single stranded DNA oligos with Gibson assembly to augment Golden Gate cloning workflows in a process called "oligo stitching". Our results show that oligo stitching can efficiently convert Golden Gate parts between different assembly standards and directly assemble incompatible Golden Gate parts without PCR amplification. Building on previous reports, we show that it can also be used to assemble de novo sequences. As a final application, we show that restriction enzyme recognition sites can be removed from plasmids and utilize the same concept to perform saturation mutagenesis. Given oligo stitchings versatility and high efficiency, we expect that it will be a useful addition to the molecular biologists toolbox.
