STRAINVIEWWhole genome sequencing of microbial isolates

Our whole-genome shotgun sequencing platform is an ideal, high-throughput method for generating draft-level genomes of hundreds or thousands of cultured isolates in parallel.

Every StrainView project includes a complimentary Core Analysis™ Report featuring raw data, assembled contigs, comparative genomics visualizations, and annotation of genes and functions including antibiotic resistance genes and virulence factors.

Compare Microbial Genomes with Whole-genome Shotgun Sequencing

Strainview allows you to characterize your entire strain collection comprehensively and efficiently.

Our approach uses high-coverage DNA sequencing on the Illumina or PacBio platform followed by genome assembly to produce annotated draft-level assemblies with contigs of hundreds of kilobases.

Our standard strain analysis assay provides 300 megabases of sequencing data per isolate, equivalent to 60x coverage of a 5 megabase-pair bacterial strain.

Diversigen’s customers receive an interactive online report featuring raw data, assembled contigs, comparative genomics visualizations, and annotation of genes and functions including antibiotic resistance genes and virulence factors.

Antibiotic Resistance and Functional Repertoire Annotation

Strains with identical 16S marker genes can have highly divergent metabolic traits and functional content in the rest of their genomes1. This means that researchers relying on 16S sequences alone to characterize their strain banks may be missing large amounts of potentially important functional diversity.

Historically, a common approach to characterizing strains has been to perform full-length Sanger sequencing on the 16S ribosomal RNA gene. This approach is limited in what information is provided about any given strain; such as the functional content of that strain’s genome.

Diversigen’s analysis provides a full characterization of functional content in strains in a high-throughput manner, while also providing taxonomic identity using the entire genome content.

Create a Custom Strain Database for Research

You can also use our isolate genome assembly service to create a fully-annotated custom strain database for your own research purposes. Diversigen can include a customer’s isolates in a private, firewalled reference database for use with ​shallow ​or ​deep shotgun sequencing sequencing projects.

StrainView™ Basics

Suggested Sample Types

We have experience working with a wide array of samples types, some of the most common types that are suitable for Strain Analysis are listed below. Contact us if your sample of interest is not represented here. We recommend pelleting isolate samples prior to freezing to avoid unintentional dilution of genomic DNA into a liquid storage buffer when cells are lysed during freezing.

  • Isolates, strain libraries and pure cultures
  • pre-extracted DNA (for the best data quality, please allow us to perform the extraction)
