Custom Monoclonal Antibody Inquiry


We don’t operate like typical antibody providers who take custom projects and outsource them to other companies. When that happens, you lose control of the process, quality, and your peace of mind.

Our manufacturing facilities and staff are in one location in the United States, and a team of skilled scientists is dedicated to your project – from start to finish. Our scientist ensures the highest level of quality, responsive project management, and protection of the supply chain. That is why companies and researchers have trusted us for nearly 50 years.

Our milestones are heavily weighted to achieve a successful finished project, ensuring turnkey use in your application(s). Our scientific team works with you throughout each milestone phase to provide personal service and customized results.

All projects utilize target-specific B cell selection, which yields robust numbers of recombinant rabbit monoclonal antibody candidates for screening.
