Rabbit Monoclonal Antibodies

Ethically source your custom monoclonal antibodies. Our onsite vivarium, 2 GMP facilities, and staff veterinarian enable us to offer custom antibody development for multiple species.

Human Monoclonal Antibodies

Enjoy the seamlessness of our human antibody engineering services, complete with ELISA screening, sequencing, cloning, transfection, and the safe delivery of your fully human antibody.

Antibody Production Services

Leverage over 2 decades of antibody experience and benefit from a complete offering with both in vivo and in vitro monoclonal antibody production services.

Hybridoma Sequencing

Get your custom antibodies in mass quantities thanks to our powerful high-throughput hybridoma technology and Next Generation Sequencing (NGS) validation.

Bispecific Antibody Production

Generate custom bispecific antibodies using cutting edge technology, sophisticated engineering, in silico 3-D-modeling and synthetic biology.

Recombinant Antibodies

Benefit from recombinant antibodies which offer improved consistency, specificity, and scalability with in vitro production of monoclonal antibodies containing a synthetic gene of your choice.

Rabbit Polyclonal Antibody Production

Partner with leaders in antibody development and customize your polyclonal antibody production from peptide design and rabbit immunization through to western blot screening and titer evaluation.

Affinity Tune-up & Humanization

Humanize your antibody by replacing its non-human antibody structures and reduce the immunogenicity of monoclonal antibodies derived from non-human sources, improving efficacy, safety, and activation within the immune system.
