Diagnostic
Polyclonal antibodies with high-avidity profiles suitable for ELISA, LFA, antigen capture assays, and quality-controlled large batch production.
Polyclonal Antibody Services
Looking for high-performance polyclonal antibodies designed around your target, not around a predefined package?
At CER Groupe, we don’t force customers into standard rabbit-only or peptide-only polyclonal packages. Instead, we start with your target and intended application, then help you select the most appropriate species, immunization strategy, and purification approach. Our teams co-create the development plan with you to ensure the antibody profile matches your diagnostic, biotechnology or research requirements.
With an ISO9001-certified infrastructure and one of Europe’s largest in-house animal facilities (12 species, including rabbits, goats, sheep, pigs, cows, chickens and rodents), we deliver polyclonal antibodies tailored for sensitivity, specificity and long-term reproducibility.
Why Choose CER Groupe?
A strategy built around your application
We guide you through epitope design, immunogenicity considerations, species selection and purification routes to ensure the final polyclonal antibodies fit your exact downstream use — ELISA, lateral flow, Western blot, flow cytometry, immunofluorescence or customized assays to ensure bioequivalence or conformity in your specific application.

3. Immunization
Fast-track or standard protocols in multiple species.
4. Monitoring & Sampling
Titer evaluation, optional QC testing.
5. Purification
Protein A/G or antigen-affinity based on specificity needs.
6. Delivery
Purified antibodies + CoA + project report + optional long-term storage.
