Missing persons cases present a significant challenge to law enforcement and to forensic science due to high numbers of open cases, and DNA samples being old, exposed to harsh conditions, and often containing degraded DNA.
Older technology utilizing capillary electrophoresis require the starting DNA to be in fairly good condition, due to the size of the short tandem repeat (STR) amplicons being interrogated. In other cases there is insufficient starting DNA to obtain a usable STR result, and specialized testing using mitochondrial DNA (mtDNA) may be the only option.
The widespread application of next-generation sequencing (NGS) in numerous areas of molecular biology research and applied sciences now allows forensic scientists worldwide to harness the full power of targeted NGS to address challenging missing persons cases.
Illumina sequencing by synthesis (SBS) technology offers a massively parallel approach for sequencing forensic PCR amplicons, both nuclear and mitochondrial. NGS enables scientists to utilize a single platform and optimal workflow to overcome the widest range of difficult samples often encountered in missing persons cases.
Our forensic genomics solution includes a dense set of identity SNPs, phenotypic SNPs, and biogeographic ancestry SNPs to assist in facial reconstruction and to eliminate candidate identifications.
Illumina offers a complete, fully validated DNA-to-data solution designed for forensic genomics. Our recommended workflow on the MiSeq FGx System can quickly deliver results, potentially speeding up investigations.
Achieve high resolution and exceptional accuracy from as little as 1 ng of DNA. With targeted sequencing of nuclear or mtDNA, you can develop more thorough, detailed profiles, even from degraded, mixed, and limited samples.
