Verogen offers software to simultaneously analyze several forensic STRs and SNPs in a single test at the same time.
Simplified STR & SNP Analysis
A high number of forensic laboratories presently use PCR and capillary electrophoresis (CE)-based techniques to investigate short tandem repeat (STR) markers and alternative polymorphisms.
Sequencing STRs allows an extra degree of resolution for identifying the variations between individuals, such as the ability to observe intra-STR single nucleotide polymorphisms, or SNPs.
SNPs can be utilized for identification when DNA is too degraded for STR analysis, or to deliver biogeographical and physical estimation for investigative intelligence.

Benefits of STR & SNP Analysis with NGS
- Alleles of identical sizes, but different sequences can be resolved through STR sequencing.
- Several polymorphisms can be analyzed at once using high throughput sequencing.
- Different types of STR can be investigated simultaneously, with no requirement for the re-testing of SNPs to deliver investigative intelligence
From DNA to Identification
When human identification is critical, you need a technology that yields effective investigative intelligence from a DNA sample. Verogen delivers a host of capabilities specific to the MiSeq FGx Forensic Genomics Solution, such as:
- Forensic genetic genealogy—Broaden the network of information to find an individual
- Mitochondrial DNA sequencing—Acquire additional answers from difficult samples
- STRs and SNPs sequencing—Estimate physical characteristics
This overview describes how these exclusive capabilities optimize the analysis of DNA, from producing a profile to discovering human identification.
STR and SNP Sequencing Workflow
Verogen provides a complete, fully validated DNA-to-data solution created for forensic genomics. Forensically relevant SNPs and STRs are PCR amplified at the same time, with indexed adapters included in every amplicon in an individual round of PCR.
The ensuing generation of DNA clusters and sequencing by synthesis is carried out using the MiSeq FGx Instrument. The sequencing data can finally be analyzed and interpreted off-line utilizing the ForenSeq Universal Analysis Software.

About Verogen, Inc.
Introducing the world’s first sequencing company solely dedicated to forensic science. Forensic laboratories are unique, and require unique scientific solutions.
We get this. Because we live it. We create thoughtfully tailored genomic solutions for forensic DNA labs. The kinds of tools we longed for when we worked in those labs ourselves. We formed an independent company with dedicated resources because we believe it’s the best way to fully address those unique needs.
The last few decades have seen tremendous advancements in molecular biology techniques, such as massively parallel sequencing. While our colleagues in other scientific fields have embraced and benefited from these improvements, forensic genomics has yet to realize the potential of the evolved technology. It’s time we had modern tools tailored to our needs.
Verogen understands this. Our sole focus is to advance science to help unlock the true potential of forensic genomics. Powered by Illumina technology and free of legacy method allegiance, we are uniquely positioned to support forensic labs with innovative solutions purpose-built for the challenges of DNA identification. Working in partnership with the community, we can elevate the forensic genomics lab’s role in preserving public safety—and improve global justice for all.
