Dundee is one of the most exciting and dynamic biomedical and life sciences communities in the UK. This small city is home to the University of Dundee, one of the leading universities in Europe for research in life science, and our neighbours are a unique mix of international academics and leading life sciences companies revolutionising the way the world views this small northeast corner of Scotland.

The patented technology underpinning Cypex’s products was developed at the University of Dundee during a five-year project in partnership with a number of leading international pharmaceutical companies. The technology enables the expression of human drug-metabolising enzymes in bacteria, without the need for large modifications to be made to the proteins.

Since the release of our first recombinant cytochrome P450 (CYP) in early 2000, we have rapidly expanded our portfolio to more than 100 products covering human drug-metabolising enzymes (including CYPs, SULTs, UGTs, CES and AOX), mouse, rat, monkey, pig and dog CYPs, fine chemicals for use as substrates, metabolite standards and inhibitors, and a range of antibodies. We have also obtained the prestigious ISO 9001 quality accreditation.

Drawing on our expertise in expressing recombinant cytochrome P450s (CYP) and in drug metabolism, we also offer a bespoke service for custom protein expression and the production of drug metabolites.

To complement our high-quality products, we have maintained close links with the University of Dundee and the industrial members of the consortium involved in the original project. This enables Cypex to remain at the forefront of in vitro drug metabolism technology.

We work with international pharmaceutical companies and world-leading academics to provide relevant tools to give reliable early insight during initial stage drug development and research studies. Here’s what they have to say about working with us.

Our Lead Scientists

Michael Pritchard

Michael’s academic background speaks for itself.  A graduate of the University of Cambridge, with post-graduate degrees from the University of Aberdeen, Michael was awarded a Royal Society Fellowship that offered a postdoctoral research fellow post at the Centre du Médicament in the French town of Nancy.

When he returned to the UK, Michael held a fellowship role with the University of Dundee, and continues to play an active role in education by hosting an annual event for local students from Abertay University to find out more about the research methods developed at Cypex.

Michael is an active member of the International Society for the Study of Xenobiotics (ISSX) and keeps up to date with advances in technologies and approaches by sharing knowledge with industry peers.

With a keen interest in family heritage and finding out more about his own family tree, Michael’s thorough approach will no doubt unearth some treasures!

Michael Voice

With a degree in Biochemistry from the University of St Andrews, Michael went on to study his Ph.D at the University of Dundee, and undertook postdoctoral research fellow posts at the University of Edinburgh and the University of Dundee.

His love of learning extends to his role as a student industry supervisor, providing CASE Ph.D students with enhanced training and the benefit of his years of industry experience.  He has the ability to share complex methodologies in a simple and engaging way, reflected in his commitment to mentoring new talent and sharing knowledge with industry peers.

Michael enjoys working closely with customers to get a comprehensive understanding of their projects to develop the right solutions to overcome their challenges.  His academic knowledge is kept up-to-date by regularly attending industry events and conferences to learn more about modern technologies and approaches.  He has been a member of the ISSX finance committee for a number of years.

When not in the lab, Michael can be found in the air or on a rugby field! Michael holds a private pilots license and is a regular at the local airstrip in Dundee, and has coached youngsters on the rugby field for over 10 years.
