Notes to Editors

Avacta Group plc (www.avacta.com)

Avacta's principal focus is on its proprietary Affimer^® technology which is a novel engineered alternative to antibodies that has wide application in Life Sciences for diagnostics, therapeutics and general research and development.

Antibodies dominate markets worth in excess of $50bn despite their shortcomings. The Affimer technology has been designed to address many of these negative performance issues, principally: the time taken to generate new antibodies, the reliance on an animal's immune response, poor specificity in many cases, and batch to batch variability. The Affimer technology is based on a small protein that can be quickly generated to bind with high specificity and affinity to a wide range of protein targets.

Avacta has a pre-clinical biotech development programme with an in-house focus on oncology and bleeding disorders as well as several partnered development programmes. Avacta is commercialising Affimer reagents through custom Affimer services to provide bespoke solutions to customers and via a growing on-line catalogue of Affimer reagents.
