– Long-term partnership to facilitate cancer research through development of custom antibodies
– Agreement to enable global access to resulting reagents and potential diagnostics

London, UK and Cambridge, UK – Today, Cancer Research UK, the world’s largest
independent funder of cancer research and Abcam plc, a global innovator in life science reagents and
tools, are pleased to announce a new partnership for the development and commercialization of novel
custom antibodies to support the acceleration of cancer research.

Under the terms of the partnership, Abcam will develop custom protein-based reagents to targets
identified by Cancer Research UK-funded researchers. The resulting antibodies will support research
to further the understanding of cancer biology, help generate new diagnostic tools, and potentially be
the basis for novel therapies.

Tony Hickson, CBO at Cancer Research UK, said: “We are excited to be partnering with Abcam to
expand our access to biological reagents and to create the tools our scientists need to help accelerate
our understanding of cancer. Abcam’s antibody development capabilities and “end-to-end” expertise
will help provide our researchers with antibody reagents that can be applied from early-stage R&D
right through to the clinic.”

Dr John Baker, SVP Product Portfolio Innovation at Abcam, commented: “We are proud to be working
with Cancer Research UK to support their scientists and to provide them with access to specific and
validated reagents to help them achieve their next breakthrough faster.”

Abcam will, upon request, supply unique antibodies developed within the terms of the agreement to
Cancer Research UK-funded researchersfor an agreed period of exclusivity in relation to that antibody.
Subsequently, Abcam’s global supply capability and co-location in major technology hubs throughout
the world will enable these innovative reagents to be made readily accessible to the wider research
and diagnostic development community.
