Metagenomics: powerful analyses of microbial communities
Molecular metagenomics is used to analyze a community of organisms as a whole; as such, it provides an exhaustive assessment of a complex ecological niche. It is a powerful, innovative approach for characterizing the genes and thus the biological functions in a given microbiome.
Metagenomics has many advantages:
- Removal of the bias associated with PCR approaches
- Culture-free analysis and direct sequencing of microorganisms
- The functional description of a whole ecosystem
Applications
Metagenomics and human health
Metagenomics and the environment
In credit to its very detailed analysis of microbial communities present in the natural environment, metagenomics can be applied to the analysis of water quality, the development of biofuels and agrochemical products, soil remediation and the development of new practices in agriculture and animal husbandry.

Targeted sequencing - An in-depth analysis of regions of interest
Targeted sequencing allows specific analysis of targeted genes (or gene regions) on many samples in parallel. With NGS sequencing on MiSeq®, NextSeq500® or Hiseq® platforms, multiple genes can be evaluated with a smaller data volume, which is easier to manage and analyse than WGS datas.
Applications
Sequencing or targeted resequencing can achieve very specific objectives:
- Screening of genomic regions of interest.
- Complete coverage of coding regions, with a limited volume of genomic data.
- Analysis of microbial genes.
GenoScreen - Services provided
Amplicon sequencing
A number of the target regions are amplified by PCR, using the initially defined specific primers. The amplicons obtained are then sequenced by NGS, following the addition of sequencing adaptors. Multiplexing approaches enable us to sequence several amplicons from different samples in parallel.
The Metabiote® solution
Metabiote® is a dedicated, innovative, optimized, standardized solution developed by GenoScreen. It integrates targeted metagenomic analysis of microbial communities.
- A library preparation methodology that limits between-sample bias.
- A diverse range of targets:
• bacterial targets: 16S rDNA
• fungal targets: 18S, ITS1 and/or ITS2 rDNA - A bioinformatics pipeline that has been optimized and automated for high-precision analyses, easy comparisons and statistical analyses, and a high degree of responsiveness.
Exome sequencing
This type of sequencing is essentially used to:
- Screen for mutations in genes involved in regulatory pathways
- Screen for mutations (SNPs, indels, etc.) associated with a particular disease (cancer, coagulopathies, etc.).
We use the NimbleGen SeqCap EZ protocol (Roche) for exome sequencing.
Personalized sequencing
After custom probe design, your regions of interest are enriched prior to sequencing which simplifies the subsequent data analysis. This protocol can be set up for any organism with an available reference genome.
GenoScreen's assets
- A dedicated team of scientists for each project.
- Comprehensive support with the elaboration of an experimental plan and project implementation.
- Assistance with data handling and interpretation of the results.

Transcriptomics - Analyzing gene expression
High-throughput sequencing of the transcriptome (RNA-Seq) has revolutionized the quantitative and qualitative analysis of prokaryotic and eukaryotic organisms.
RNA-Seq significatively enables differential expression analyses:
- Measurement of the relative abundance of transcripts.
- Identification of the genes expressed differentially in various groups (tissues, treatments, etc.)
Applications
Transcriptome sequencing provides a complete, objective analysis of messenger RNAs:
- Differential expression: assessment of variations in the expression of several transcriptomes.
- Annotation of a transcriptome against a reference database.
- Identification of all specific sequences of the studied transcriptome.
- SNP analysis.
GenoScreen - Services provided
Two methods are used to enrich the RNA fraction of interest (mRNA) prior to cDNA synthesis and library preparation:
- Poly(A) capture (for eukaryotic total RNA).
- RNA depletion (via capture with complementary probes) and mRNA enrichment (for prokaryotic or eukaryotic total RNA).
Most of our RNA-Seq libraries are sequenced on Illumina® HiSeq®4000 systems.
GenoScreen's assets
- A dedicated team of scientists for each project.
- Assistance with elaborating the experimental plan and sequencing strategy.

An analysis of whole-genome sequencing data provides a precised description of any type of organism and thus addresses a very broad range of research questions.
Applications
Whole-genome sequencing addresses important research questions in many sectors (healthcare, nutrition, agrifood, environment, etc.):
- Description of an organism’s genes and how they are organized.
- Quantification of diagnostic or phenotypic biomarkers.
- Screening for susceptibility/adaptability/resistance genes.
