High Throughput Sequencing

16S rRNA Amplicon Sequencing

Sequencing of targeted variable regions (V3-V4) in the 16S ribosomal gene allows for determining the bacterial components of microbial complex communities. Data provided include a relative abundance of taxa at the genus/species level, alpha and beta diversity calculations and basic analysis of significantly over or underrepresented groups.

Whole Genome Shotgun (WGS) Sequencing

WGS sequencing generates high depth sequence data (>10M sequences per sample) of entire microbial communities for higher resolution taxonomic characterization compared to 16S rRNA sequencing, providing species/strain-level information and community functional potential (enzymatic pathways and gene families). WGS can also be applied to isolated microbial strains to generate genomic sequencing data.

RNA Sequencing

Total community meta transcriptomics generates sequencing data from genes being actively expressed across community members. RNA sequencing can also be used to target host-specific factors, or to characterize changes in the expression of individual bacterial strains in culture.

Shallow WGS Sequencing

Whole Genome Shotgun (WGS) sequencing performed at a lower sequencing depth (>1M reads per sample) is a cost-effective method to acquire species/strain-level taxonomic characterization of the more abundant members of complex microbial communities. By sequencing at a lower depth, the cost of sequencing is reduced, however, this will reduce the ability to accurately assess the identity or potential function of low-abundance community members. This approach is offered as a lower-cost alternative to WGS sequencing while providing higher taxonomic depth than standard 16S rRNA amplicon sequencing.

Quantitative (q)-PCR

Standard qPCR

The method is based on the conserved 16S rRNA gene present in all bacteria (a comprehensive list of 16S rRNA sequences from gut bacteria have been deposited and categorized in the Ribosomal Database Project II ). By calculating the number of conserved 16S rRNA genes, qPCR can indirectly indicate the number of bacteria present in a given sample. Additionally, appropriate design of qPCR oligonucleotide probes (primers) that can identify the sequence of the 16S gene variable regions allows for the amplification of genes from a specific bacterium of interest whilst excluding all other bacteria, making qPCR a useful tool for quantifying specific bacteria in a complex microbial community.

Fluidigm Access array targeted high-throughput qPCR

The BioMark™ Systems paired with the Fluidigm Dynamic Arrays are an efficient solution for large-scale, real-time qPCR. The nanofluidic chips contain fluidic networks that automatically combine sets of samples with sets of assays. This innovative solution for real-time qPCR provides reaction densities far beyond what is possible with microtiter plates and significantly reduces the number of liquid-handling steps and the volume per reaction.
