Founded in 2000 in Grenoble, France, Protein’eXpert is an expanding contract research organization devoted to recombinant protein engineering and production. Our 50-member staff offers custom-designed services focusing on the discovery, optimization, and production of valuable target or therapeutic proteins.

Since 2004, Protein’eXpert has extended its offering to the biomanufacturing of therapeutic protein and recombinant vaccines for early clinical trials through its integrated subsidiary PX’Pharma. PX’Pharma provides dedicated contract services for process development and scale-up optimization as well as preclinical and clinical CGMP manufacturing.

Integrated Organization for Seamless Transfer

We differentiate from other protein CMOs by our integrated way of working from early stage research to phase 1 and phase 2 clinical production. This original approach ensures seamless transfers and therefore leads to significant reduction in protein development–related budget and time. Our programs are set up to ensure optimal transfer to partner CMOs offering largescale facilities for phase 3 and market production.

Acknowledged Expertise in Protein R&D

We have demonstrated our capability in tackling highly complex and recalcitrant protein projects and in taking them to production stages. We have worked on more than 500 proteinrelated projects for 120 European and American clients.

A Collaborative Way of Working

At Protein’eXpert, we are used to working collaboratively with our clients and partners. Past experience has demonstrated that our friendly style of interaction and research-driven approach allow us to set up trusted and productive relationships.

Project Management

We assign a dedicated project manager to all research and manufacturing programs. This person is responsible for coordinating the development team associated to a project as well as ensuring that timelines are observed and objectives are reached. The project manager also maintains transparent and efficient communication with our customers through regular updates on their program progress and by quickly addressing their questions and needs.

Quality Assurance and Regulatory Support

The whole organization works toward quality standards to ensure that its business and production processes generate maximum performance and meet customer satisfaction. Protein’eXpert complies with ISO 9000:2000 international quality standards. All work at PX’Pharma is performed according to international regulatory GMP guidelines (ICH, EMEA, and FDA).
