Custom antibody development against haptens and membrane receptors

Stay relaxed.

SYnAbs' custom monoclonal antibody generation service is a one-stop shop solution allowing the generation of high quality specific antibodies for in-vitro diagnostic, R&D and therapeutic purposes. We run dozens of projects per year with high success rate for the raising of anti-drug antibodies, surrogates antibodies, or therapeutics mAbs from antigen design to gram manufacturing.

More species. More challenged immune repertoires. More diversity.

Stop wasting time & money !

Maximizing the success rate and the quality of your generated monoclonal antibodies in mice, alpagas, and SYnabs proprietary rats-LOU with parallel multi-species approach. Rat-LOU is known to be a particularly good responder to small molecules.

The diversity of the natural in-vivo immune repertoire is the key to the generation of higher affinity unprecedented monoclonal antibodies.

In need of a humanized mouse model? SYnAbs can work with you to access the complete functional human antibody repertoire through Alloy Therapeutics' ATX-Gx platform.

Strategic immunizations. Variety of schedules and injection routes.

SYnabs has developed a variety of immunization types including chemical, peptide, proprietary SYnDNA immunization, SYnCell immunization, also with our in-house special adjuvant to boost the immune response.

SYnAbs offers variable immunization schedules and injection routes to benefit from natural antibody maturity, while breaking immune tolerance for small molecules, peptides and low-immunogenic compounds.

Thanks to smart antigen design strategies, SYnabs direct the immune response towards the most appropriate epitope. As a complete service, SYnAbs is able to design, synthesize and conjugate antigens for use as immunogen for your monoclonal antibody development program.

Targeting

Effective multiple screening.

SYnabs has developed unique capabilities to isolate rare B populations from both primary and secondary lymphoid organs of the immune system.

Applying screening to hundreds of millions of enriched antibody-secreting plasmocytes cells, SYnAbs selects the rare antibodies with the desired unique effector properties you are looking for.

Neutralizing? inhibitor? agonist? antagonist? Make your choice.
