High Peak

The High Peak, UK facility is a specialist biotechnology site with proprietary Cell Microarray Technology located in the heart of the UK’s Peak District national park. This site provides unique receptor ID/off-target screening services to accelerate, inform, and improve the safety of the discovery and pre-clinical development process for clients. We are recognized as leading technology within the biotherapeutic field.

High Peak is located within 10,000 ft2 of purpose-designed laboratories and offices. We currently have over 50 Employees on site.

Core Tech Building - High Peak

Founded as Retrogenix in 2008

Acquired by Charles River Laboratories to expand the Discovery and Safety portfolios in 2021

Possesses the largest, most unique and high-quality set of human cell surface and secreted proteins (>6,300) expressed in human cells

Identifying precisely how a biological or chemical entity interacts with the human cell is fundamental to furthering our understanding of both normal biological and disease processes as well as revealing the mechanism of action of drugs and their potential for toxicity. The Retrogenix Cell Microarray Technology provides a fast, accurate and effective solution for discovering the human cell surface and secreted protein targets of antibodies, proteins, viruses and small molecules.


This allows our global pharmaceutical clients to:

overcome the critical deconvolution step in phenotypic drug discovery
uncover novel, high quality and exploitable drug targets
explore safety liabilities of lead candidates using the most comprehensive human expressed off-target system
High Peaks biologically-relevant system detects specific interactions with a high degree of sensitivity.


This unique tool uses proprietary arrays of expression vectors – encoding over 6,300 full-length human plasma membrane and tethered secreted proteins – spotted onto slides. Human cells grown over the top become reverse-transfected resulting in cell surface expression of each respective protein at distinct slide locations. The test molecule is applied, and specific binding analysed and confirmed using an appropriate detection system.
