Looking for a partner who can design the exact antibody you need, not force you into a standard package?
At CER Groupe, we believe that antibody discovery should start with your target and your application, not with a predefined catalogue of immunization packages. With more than 25 years of expertise, an ISO9001‑certified platform, and an in‑house animal facility hosting 12 species including llamas, we work side‑by‑side with you to design the most efficient route to the antibody you require.
Whether you are developing a diagnostic assay, a biotherapeutic research tool, or a novel biosolution for agrifood, our teams help define the optimal strategy: species, immunization approach, screening technologies, formats, engineering options and production readiness.
Why Choose CER Groupe?
A partner that adapts to your target, not the opposite
Instead of imposing a predetermined workflow, we build a custom design plan with you, starting from your target and intended application. This includes antigen design support, species selection, screening depth and format choice.
