Schematic representation of an IPCR amplicon resulting from digestion, self-circularization and amplification of DNA flanking a resistance gene.
Mobile genetic element is digested with restriction enzymes and self-ligated into a circular molecule (1) and amplified (2). The IPCR amplicon contains the up- and downstream regions surrounding the target ARG, which have MGE associated genes (mge1-5) and co-selected ARGs (co1 and co2). The digestion and ligation site separates the up-and downstream regions of the ARG in the IPCR amplicon.
