Your Bioanalytical Services Powerhouse

Bioassay, a Reaction Biology Corporation, offers GMP potency assays and functional bioassays, both in vitro and in vivo, as well as GLP compliant services. Through our sister company PSL, Peptide Synthesis Services, we can also provide peptide-specific antibody production and neoantigen synthesis. 

We are a trusted provider of development, validation and routine bioanalytical assays for global players and biotech companies in the pharmaceutical, chemical and cosmetic industries. 

We develop and perform GMP potency assays for a wide variety of drugs and biologics, including proteins, monoclonal antibodies, vaccines and gene therapies. Our team of experts works with clients to select the most appropriate assay format and design a robust, QC-friendly and sensitive method. We follow GMP and ICH guidelines to validate potency assays, and offer routine GMP potency QC testing to support upscaling and manufacturing validation processes, as well as batch release and stability testing to monitor product potency over time.

Join Us for an Expert Session at Festival of Biologics!

Speaker: Dr. Axel Hohenstein, CSO and Managing Director
Topic: Advancing Peptide Therapeutics: Cell-Based Potency Assays for GLP-1, GLP-2, and GIP Receptor Agonists
Date & Time: October 1, 12:50–1:10 PM
Location: Theatre 7

Peptide-based drugs are transforming the treatment of metabolic disorders, and GLP-1, GLP-2, and GIP receptors are at the forefront of next-generation therapies. In this session, Dr. Hohenstein will share how Reaction Biology’s custom peptide synthesis and robust cell-based potency assays enable precise IC₅₀ determination, support dual-receptor strategies, and meet GMP standards for batch release testing.

Join us to learn how our platform accelerates peptide drug development from early discovery through clinical readiness.
