Tests and Assays  ...back

We offer you:

Dear customer,

INVITRO-CONNECT GmbH offers you a large data base with various tests and assays for registration and research & development of chemicals, pharmaceutical substances, cosmetics, biocides, pesticides, medical devices and of veterinary medicinal products. These are usually carried out under GLP (good laboratory practice) in an accredited test laboratory.

Furthermore we also offer all in vitro tests approved by the ECVAM as animal testing alternatives.

From the development of an excellent test strategy, over the project management and laboratory coordination to study monitoring, toxicological expertise and GLP inspections at the affiliated laboratories.

We provide final test reports including the registration dossier, of course in the format of your choice, digital as well as on paper and worldwide.

Benefit from our wide range of expertise, our experienced collaborators and an international well established network of partners: thoroughly selected experts, toxicologists and more than 80 accredited testing laboratories with an over 20 years' track record in the industry.

INVITRO-CONNECT GmbH puts together the right team for each project. Thanks to our familiarity with the laboratories and the experts, we commission those most suited for the specific service. That way we can guarantee high-quality results.

We fully advise and support you with our expertise and the expertise from our whole global cooperation network.

We offer you all tests and services with the best price-performance ratio.

We are happy to also be your service provider and support your projects reliably –as we already do for many other satisfied clients.

For further information or interest in collaboration with us please do not hesitate to contact us personally. We are pleased to be of service to you.

Testung auf endokrine Eigenschaften nach OECD

Die endokrinen Disruptoren (endokrin aktive Substanzen EAS) sind in den letzten Jahren immer mehr in den Fokus der Öffentlichkeit geraten, da sie durch ihre hormonähnliche Wirkung schon in den niedrigsten Konzentrationen Auswirkungen auf die Organismen in der Umwelt zeigen.

2002 wurde von der EDTA (OECD Endocrine Disrupter Testing and Assessment Task Force) das ,,OECD Conceptual Framework for the Testing and Assessment of Endocrine Disrupting Chemicals“ eingeführt, welches fünf verschiedene Untersuchungsstufen für die Risikobewertung für diese  Substanzen vorgibt:

Level 1
Analyse der existierenden Daten

Level 2
Untersuchung eines einzelnen endokrinen Mechanismus durch in vitro Studien

Level 3
Untersuchung eines einzelnen endokrinen Mechanismus durch in vivo Studien

Level 4
Untersuchung von multiplen endokrinen Mechanismen durch in vivo Studien

Level 5
In vivo Langzeitstudien

Wir unterstützen Sie bei der Testung von endokrin wirksamen Substanzen mit folgenden Studien:

Level 2

  • Östrogen- und Androgen Rezeptorbindungsaffinität (YES/YAS Assay)

Level 4

  • Fish Sexual Development Test (OECD 234)

  • Fish Reproduction Partial Lifecycle Test

  • Sediment-Water Chironomid Toxicity Using Spiked Sediment (OECD 218)

  • Sediment-Water Chironomid Toxicity Using Spiked Water (OECD 219)

  • Daphnia Reproduction Test (OECD 211)

  • Earthworm Reproduction Test (OECD 222)

  • Sediment Water Lumbriculus Toxicity Test (OECD 225)

Level 5

  • Fish Life Cycle Test (Danio rerio) (OECD DRP 2008)
