About Avacta

Avacta was spun-out from the University of Leeds in 2004 by its current
management team as a biophysics company, with the aim of combining the
disciplines of physics and biology to develop innovative technologies and
expert technical services to address unmet needs in the biopharmaceutical and
healthcare sectors. Avacta has a core bio-analytical technology development
programme addressing the needs of the biopharmaceutical sector to fully
characterise their new products at the earliest stage in their development to
reduce the risk of late stage failure. High end analytical instruments and
leading edge contract research services are being provided to the
biopharmaceutical and healthcare/personal-care materials sectors through the
Group's biotech support division, Avacta Analytical. High value solutions for
rapid, point of care diagnostics based on these core bio-analytical
technologies, with a near term focus on veterinary diagnostics, are being
delivered through Avacta Animal Health. Longer term these technologies will be
transferred into the human clinical diagnostics market. Avacta listed on AIM in
August 2006.
