SEDIAG Presentation

The main activity of SEDIAG is the production, development and marketing of diagnostic kits for various agricultural and biotechnological applications..

SEDIAG offers a testing service for rapid and reliable diagnostic assays in phytopathology..

SEDIAG also produces and develops monoclonal antibodies against various pathogens, viruses, proteins or synthetic peptides, on request. This service includes all steps from animal immunization to the development of a diagnostic ELISA test.

SEDIAG will provide assistance and advice, as well as training courses, on request.

Research & Development

A recognized know-how in immunotechnology is the foundation of SEDIAG..

We are specialized in the production of monoclonal antibodies for developing highly specificimmunoassays for various applications in biotechnology and diagnostic testing.

Custom production of immunological reagents and monoclonal antibodies can be undertaken for private or public research laboratories.

ELISA protocols can be developed for customers interested in particular immunoassays or routine diagnostic applications.

SEDIAG is also totaly involved in several R&D projects and especially in the European FP7 project (R4SMEs) MYCORRAY which aims to create a Cost-Effective Hand-Held Device For Grapevine Trunk Diseases Detection (project details are available on the following website :  http://www.mycorray.eu/)




The National Institute for Agronomic Research (INRA) is ranked the number one agricultural institute in Europe and number two in the world, INRA carries out mission-oriented research for high-quality and healthy foods, competitive and sustainable agriculture and a preserved and valorised environment. Since September 2006, SEDIAG benefits from an exclusive contract for the commercial exploitation of INRA Know-How concerning the manufacture and commercialization of immuno-chemical kits for vegetal pathogens detection.



Vitagora is France’s leading innovation network dedicated to Taste Nutrition & Health, that assists its food industry and research members in the development of innovation projects with cutting edge R&D programs. According to this dynamic, the project entitled “Food Risk Management associated with cereal mycotoxin contamination : Diagnostic and Preventioninvolves SEDIAG and the cereal cooperative Dijon Céréales.



Dijon Céréales is among the main agricultural and agroalimentary group of Burgundy – Franche-Comté. It draws its future by putting a lot for a long-lasting and responsible agriculture and into the innovation of transformation products. Dijon Céréales group gathers several companies and collaborates to the union of cooperative around 5 main jobs :

  • Cereals (collect and supply),
  •  Milling,
  •  Vegetables and onions (collect, packaging and transformation),
  •  Distribution (green areas, green entertainments, grapevine, breeding),
  •  Logistic (carriage and storage).


Abingdon Health is a company dedicated to contract manufacture of lateral flow diagnostics. Pocket Diagnostic (registered trademark) in-field tests are designed to give growers, consultants and inspectors information about plant health where and when it is needed. Disease symptoms can be confirmed in just a few minutes anywhere in the glasshouse, field or supply chain. In November 2008, SEDIAG signed a distribution agreement for Pocket Diagnostic kits in France, Spain and Morocco (see the products).
