Cyprotex launch Short Time Exposure service for identifying potential serious eye damage for new chemicals

Cyprotex PLC (AIM: CRX), a specialist ADME-Tox Contract Research Organisation (CRO), announce the launch of a new in vitro testing service, the Short Time Exposure (STE) assay for identifying potential serious eye damage from new chemicals. Cyprotex has validated and demonstrated proficiency in the assay based on the draft OECD (Organisation for Economic Co-operation and Development) test guideline released in June 2014.

A complete ban on animal testing of all new cosmetics and their ingredients sold in Europe was put into force in March 2013. In addition, the Classification, Labelling and Packaging (CLP) Regulation, the GHS (Global Harmonised System of Classification and Labelling of Chemicals) and the REACH Regulation all propose the use of in vitro alternative methods for toxicity testing. The STE method has been developed as an in vitro(non-animal) alternative to the animal-based rabbit eye test and Cyprotex are able to perform the service under GLP (Good Laboratory Practice) in order to meet the requirements of these regulatory bodies.

Dr Anthony Baxter, Cyprotex's Chief Executive Officer said, "The addition of the new STE service enables Cyprotex to test chemicals for potentially harmful ocular effects. By bringing this on board we comply with new regulatory guidance and are well placed to meet the needs of our customers for non-animal alternative testing."
