Bethyl Contract Projects – Recombinant Rabbit Monoclonal Antibodies


What sets Bethyl apart from other contract partnerships? For starters, we do not operate akin to a typical “custom” provider that outsources and has multiple teams managing various project phases. Bethyl’s manufacturing facilities and staff are all located in one facility here in the United States to ensure the highest level of excellence in our products and services that we provide to customers. We apply a CRO/CMO provider approach to each individual project, where your project objectives become our goals. A team of skilled scientists are dedicated to each project from start to finish to provide personalized care. We’re also confident in what we do based on our track record of over 45 years of custom and bulk antibody manufacturing success.

Our milestones are heavily weighted to achieve a successful finished project, which ensures turnkey use in the goal application(s). Budgets typically range from $50k-$100k depending on the nature and scale of the project. Our scientific team works with you throughout each milestone phase to ensure 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.


  • Providing mAbs that bind the desired target is not enough; they must be highly specific for their intended target
  • Our goal is to provide mAbs that perform in the requisite application(s)
  • We recognize that projects are time sensitive and require a high degree of customization
