Icosagen offers custom-tailored services for recombinant protein production in mammalian cells, and antibody development. By using patented state-of-the-art technologies, we deliver high quality products to the biopharmaceutical and diagnostic companies. Company’s quality control and assurance system is ISO9001:2008 certified.

Icosagen Cell Factory (ICF)
is a European, mammalian CRDMO, bridging the CRO and CDMO expertise, hence the CRDMO designation. We drive your protein drug candidates seamlessly from R&D phase into clinical development stages.
We focus on protein/antibody work, all the way from discovery, transient expression (mg to grams, ml to 50L) up to stable cell line and process development for GMP manufacturing, incl. analytics and DSP. Our own on-site GMP facility is in preparation and scheduled to be operational in early 2024.
With Icosagen’s modular and integrated services, from discovery till GMP material, your project stays entirely in the hands of one site, no tech/molecule transfer, constant project team, legal agreements in place, and, importantly, with your molecule knowledge remaining in house. This saves time, costs, and nerves.
