Cost-effective, species-level microbiome profiling

The Ion AmpliSeq Microbiome Health Research Assay (MHRA) is a next-generation sequencing (NGS) assay that allows for cost-effective yet comprehensive profiling of microbial diversity in the human gut microbiome. This assay offers increased resolution and specificity of species-level detection compared with traditional 16S rRNA sequencing for key organisms associated with immunological response to cancer, diabetes and autoimmune diseases, gastrointestinal (GI) disorders, and infectious diseases.

Most other commercially available 16S panels target two to four hypervariable (HV) regions of the 16S rRNA gene, while the MHRA panel targets eight out of the nine HV regions in addition to a set of high-resolution markers for increased species-level identification for highly comprehensive and sensitive microbial profiling research.

 

This targeted NGS panel, combined with integrated data analysis tools, creates a complete end-to-end solution to help both expand and simplify your microbiome research. Two versions of the MHRA are available, one is a kitted assay on the Ion GeneStudio System, and the other is a custom Ion AmpliSeq panel on the Ion Torrent Genexus System. These two versions of the assay take advantage of the different benefits offered by each NGS platform.


Easy, rapid microbial detection with NGS

While shotgun metagenomics can offer some advantages over targeted NGS, such as higher functional resolution, it is more costly and time-consuming, and requires more complex bioinformatics tools, making this approach difficult to master, potentially causing issues with data reliability and reproducibility.

 

The MHRA offers an easy to use, cost-effective, and rapid solution to detect and quantify microbes of bacterial origin in the sample by targeting 8 out of 9 hypervariable regions present in the 16S rRNA gene. The assay also provides species-level specificity to interrogate the presence of a curated list of 73 bacterial species (Table 1) that have strong scientific evidence to be implicated in immuno-oncology (I-O) response, gut health, and autoimmunity, as well as response to infection. This highly curated species-specific panel allows for 100% specificity and sensitivity (Figure 1).

 

The MHRA also offers a complete end-to-end, nucleic acid-to-report solution, with an optimized analysis workflow using Ion Reporter Software for analysis of data generated with the Ion GeneStudio system. The analysis workflow enables multi-sample analysis and visualization, such as heatmap, PCoA, relative abundance, and diversity visualization. The analysis uses up-to-date reference databases such as the curated SILVA database, the Applied Biosystems MicroSeq database, Greengenes, and NCBI.
