Binding Site provides specialist diagnostic products for detection, monitoring and analysis of certain blood cancers and immunological disorders to clinicians and laboratory professionals globally.

The UK head office houses all product development, manufacturing, global distribution and marketing. Worldwide customer support is also provided by a further seven offices in the US and Europe.



As part of its in-depth sector coverage, Nordic Capital identified Binding Site as an attractive opportunity in 2010 and proactively approached the founder, a Professor of Immunology at Birmingham University’s Medical School. As a result of those discussions, Nordic Capital entered into a bilateral dialogue to acquire the company.

Our extensive experience and deep sector knowledge helped secure the trust of the founder, who retained a minority shareholding in the company and continued to support the business after the acquisition as a member of the board and R&D Committee.

Investment rationale

  • Significant room for continued market penetration of core products.
  • Strong R&D culture and attractive product pipeline.
  • Academic origins with research focus.
  • Potential for operational improvement.

Building the business 

  • Nordic Capital recruited a strong new management team and professionalised central functions, including financial reporting and control.
  • Following a successful pilot in the US, the sales force was increased and refocused in order to increase penetration in particular market segments.
  • Nordic Capital funds made significant investment in R&D, with the Company successfully increasing the penetration of its core Oncology assays; and commercialising a new family of assays in co-operation with a leading cancer research institute.
  • The Company also placed more of its own analysers in laboratories and hospitals, transitioning more customers on to Binding Site’s proprietary instrument platforms. This led to the launch of the company’s second generation analyser, Optilite.
