Key Information

This information is provided for the purposes of AIM rule 26
Avacta Group plc (AIM:AVCT) is dedicated to providing life scientists with high quality, powerful tools to enable them to work faster and smarter in accelerating our understanding of biology and disease, and to help them apply these advances to diagnosis and treatment.
Avacta came to the AIM market in 2006 to provide instrumentation, consumables and reagents for life science researchers. The Group’s activities are now focused on Affimer® technology, an engineered alternative to antibodies, which it is commercialising through Avacta Life Sciences.
Antibodies are the gold standard affinity reagents used in life sciences and they dominate research, diagnostic, and therapeutic markets worth over $100bn despite their limitations. Antibodies generally have problems with specificity to their target, have very long development times, are limited to certain targets by the need to use animals’ immune systems in their development and are expensive to produce. There are also many important applications where antibodies struggle because of the nature of these large, complex and often fragile proteins.
“Affimer” technology is based on a small protein that can be engineered to bind with high specificity and affinity to a wide range of targets. They are generated rapidly in a few weeks without any use of animals and are easily manufactured with high yields. Their simple structure and robust nature makes them able to address applications where antibodies cannot be used, as well as being an alternative to antibodies in a wide range of applications in diagnostics, drug / biomarker discovery, life sciences research & therapeutics.


The Group is focused on delivering to shareholders, over the medium to longer term, value growth and profitability through commercialisation of its intellectual property.

The Directors believe that the Affimer affinity reagent platform provides the greatest potential for such value growth by delivering a partnered pipeline of Affimer drugs and building a profitable research and diagnstics reagents business through licensing. The Group is therefore focusing its investments primarily on its proprietary Affimer technology.

The Group also provides diagnostic tools and services for veterinarians through its Animal Health business including specialisms in allergy, acute phase proteins and cancer.
