a CDMO with a pioneering spirit

When PX’ was founded in 2000 it offered something both rare and original for its time: engineering and production of recombinant proteins.  We started off by providing proteins for research applications and supplying laboratories with products that help them test their hypotheses.


In a short time PX’ became an essential link to success for its customers’ projects. Our core values – excellence and innovation – grew out of action.

Innovation and excellence: two values that encourage development


Today a valued partner of laboratories and manufacturers all over the world, the company focused on development from the very beginning.



  • We follow and integrate the latest technologies in our platforms to offer services at the cutting edge of innovation to our customers.
  • We include the latest regulatory requirements in our procedures to guarantee our customers quality level according to the highest standards.
  • We have developed competences throughout the entire value chain: GMP, analytics, purification, quality assurance, CMC consulting… to provide the best chances of success for our customers’ projects and we have increased our production capacities.
  • We constantly recruit competent and enthusiastic men and women, building complementary teams choosing a constructive environment that values teamwork, commitment, integrity and accountability, to provide the best expertise and the best service.

A singular CDMO for the benefit of your projects


In 2012, PX’ became a subsidiary of Aguettant Laboratory.

Integration into this new world was easy as both companies share values such as exactness, integrity, and initiative.

Aguettant’s commitment to healthcare professionals strengthens PX’s pharmaceutical expertise and contributes to developing a singular biomanufacturing offer, solid from end-to-end of the health innovation chain: from the laboratory to the patient’s bed; from research to clinical trial.

This rich and original journey makes PX’ a singular CDMO and a privileged partner in giving every chance of success to your projects.
