Notes to Editors:

Retroscreen Virology Group plc ("Retroscreen") is a rapidly growing UK life sciences company pioneering a technology platform called hVIVO which uses human models of disease involving healthy volunteers to study new drugs and investigate disease in a safe, controlled environment.

Retroscreen has established itself as the world leader in this field through the provision of clinical services to third party study sponsors. To date, the Company has conducted over 35 clinical studies, involving more than 1600 volunteers for a range of leading industry, governmental and academic clients.

However, Retroscreen's hVIVO platform has a much wider application in helping to understand illness better because the Company believes that the best way to understand human disease is by studying it in humans, not laboratory models.
