Custom and Bulk Antibodies

Having the right, high-quality antibody for your application can mean the difference between success or failure, which means having to go back to the drawing board. So when it comes to selecting a partner for your custom or bulk antibody needs, it matters how and where your antibodies are made.

The way we make antibodies makes all the difference – whether you need a bulk antibody, custom protein, custom recombinant rabbit monoclonal antibody, or polyclonal antibody.

  • We de-risk your journey. Our scientists invest the time to understand your exact needs and then operate in close collaboration with your team to maximize the probability of success. Your project objectives become our goals, defined by clear milestones.

  • We make everything in-house. From the antigen to the final antibody formulation, the entire production process and quality control occur at our facilities in Texas. We manage the process from start to finish and control the supply chain, so you can have more peace of mind.

  • We care about your success. We don’t just take your order and send back an antibody that worked in a screening ELISA in our lab. Your research, your business, your reputation is too important for us to cut corners. Our scientists are passionate, experienced problem solvers. And we’re ready to get to work for you.
