Figure 1From: Ancient DNA studies: new perspectives on old samples454/Roche NGS procedure. Double-stranded ancient DNA is converted in single-stranded DNA library through the ligation of specific 454 “adapters” (A and B); the emulsion PCR amplifies the library molecules on “capture beads” that are then enriched and loaded onto PicoTiterPlate (PTP) for the pyrosequencing reaction.Back to article page
