Who We Are

WeNou is an independent company based in Lisbon and created in May 2019, joining an experienced team with strong scientific, technical, market and commercial knowledge. It is highly focused in developing new molecular biology solutions for the industry.

 

In this context, WeNou provides innovative services based on DNA analysis, specially focused in Next Generation Sequencing (NGS) technology and has ISO 17025 Accreditation.

 

WeNou was created to give answers to growing interest and concerns of all food chain stakeholders about food authenticity, safety and quality, including consumers, which demand more accurate information about the products they use. NGS meets a strong market need for reliable untargeted analytical methods that can detect several different targets at the same time. NGS application to food and feed analysis allows the reliable identification of the species content in a sample (meat, fish, plants, seafood, insects, microorganisms, etc.), providing a powerful tool for the assessment of food authenticity and safety, helping to prevent food fraud.

 

Furthermore, the universal applicability of NGS makes it suitable for use in other important areas, like environmental quality or animal health and diagnostics.

What We Can Do For You

  • We provide NGS and other DNA based analytical services mainly to the food and feed market for accessing food and feed authenticity (safety and quality), but also to the environmental and veterinary animal disease diagnostic

  • We develop new methods and define innovative approaches to better answer the new challenges our clients are facing

  • We work with clients and provide support to help to deal with problems related with their products and processes

  • We can work on specific projects on demand of our client

Our Services

Using targeted and untargeted DNA-based methods, WeNou provides services to answer the main questions related with authenticity and safety of food and feed products, as described below:

  • Untargeted approach

Identification by sequencing

Some specific genomic regions are recognized for their identification potential, as each species present unique DNA sequence, allowing to differentiate them from other similar species. WeNou worklow for species identification uses the genes that are recognized as appropriate markers according to public available scientific information. Namely:

- Mitochondrial genes COI, cytB, 12S and 16S for animals;

- Nuclear ITS2 and chloroplastidial genes , and intergenic spacers for plants;

- rRNA 16S gene and rRNA 18S genes for bacteria and fungi respectively.

These gene sequences are available in several public databases and are recommended for identification (e,g, BOLD database). Additionally, these public databases also contain a large lists of primer sequences published in scientific papers, which can be used for in-house species identification schemes.

 

Identification in complex samples by NGS

This approach is based on Next Generation Sequencing technology, a highly powerful methodology to access food and food fraud by species substitution or addition of undeclared components. It is applicable to complex and/or processed samples (e.g. meat balls, lasagnas, pizzas, herb mixes,) etc. By the end of the analysis it is possible to get a list of species of a certain group (meat, fish, bacteria, plants, etc.). The number of species that can be identified is virtually unlimited.

 

Identification in pure samples by Sanger

This identification approach is based on Sanger sequencing and is applicable to identify the species that composes a pure sample of, meat, fish, plant, bacteria etc (e.g. meat steak, plant leaves, bacteria pure culture, etc.). The result is the scientific name of the species that composes the sample. It is mostly applicable to detect fraud by species substitution in single-species products. Like NGS, Sanger sequencing takes advantage from the existence of huge databases and the number of species that can be identified is virtually unlimited.

 

  • Targeted approach
     

Detection by real-time PCR

A targeted approach requires the previous definition of the species that is intended to search for. It is applicable to assess the presence or absence of the defined species in a food or feed sample. This species may be a pathogen, an allergen, a GMO or any undeclared and restricted ingredients, like pork, soy, etc. The result is expressed as positive or negative for the target organism. Can be applied to any food or feed sample.

See here our Services and Accreditation Annex.

  • Custom Services

WeNou team has all the necessary knowledge to work on custom approaches to give answer to the specific needs of its clients. These projects may focus a broad range of topics, from, e.g. food authenticity to microbiome assessment.
