Amplicon sequencing is a highly targeted approach that enables researchers to analyze genetic variation in specific genomic regions. The ultra-deep sequencing of PCR products (amplicons) allows efficient variant identification and characterization. This method uses oligonucleotide probes designed to target and capture regions of interest, followed by next-generation sequencing (NGS).
Amplicon sequencing is useful for the discovery of rare somatic mutations in complex samples (such as tumors mixed with germline DNA). Another common application is sequencing the bacterial 16S rRNA gene across multiple species, a widely used method for phylogeny and taxonomy studies, particularly in diverse metagenomics samples.
Amplicon sequencing allows researchers to sequence targets ranging from a few to hundreds of genes in a single run. This ultra-high multiplexed PCR approach expedites research by assessing multiple genes simultaneously. Libraries can be prepared in as little as 5–7.5 hours and sequenced in 17–32 hours.
Amplicon sequencing enables a wide range of research applications for the discovery, validation, or screening of genetic variants.
Focused power for sequencing thousands of amplicons in a single run.
NGS is uniquely positioned in an infectious disease surveillance and outbreak model. Compare amplicon sequencing with other pathogen NGS methods such as shotgun metagenomics and target enrichment.
