Polyclonal antibodies (pAbs) are produced by B cells in the body’s adaptive immune system. Unlike monoclonal antibodies (mAbs), which target a single epitope on an antigen, polyclonal antibodies recognize multiple epitopes on a single antigen. These antibodies are vital in research, diagnostics, and treatment. They are used in immunodiagnostics, food quality control, and veterinary and human medicine for regular diagnostics. Additionally, polyclonal antibodies have therapeutic applications and may possess anti-inflammatory or immunomodulatory effects.
Recent advancements are accelerating the use of polyclonal antibodies in various fields. In November 2024, Sanofi announced an investment of €40 million (US$42 million) to enhance its bioproduction facility in Lyon, France. A portion of this funding will be dedicated to research and production of Thymoglobulin (anti-thymocyte globulin [rabbit]), a polyclonal antibody used in transplant care.
Additionally, in October 2024, EQT Life Sciences revealed the acquisition of ATB Therapeutics by its LSP 7 fund. The goal of this €54 million Series A fundraising is to accelerate the clinical development of novel therapeutic antibodies, advancing the company’s ATBioFarm technology.
AI integration is playing a transformative role in the development of polyclonal antibodies. AI-driven methods help predict the potential of antibodies to penetrate cells and enhance their properties such as toxicity, immunogenicity, solubility, and half-life in the body. This technology is significantly reducing the time and costs associated with drug development.
A notable example is Antiverse, a techbio startup that utilizes AI to design antibodies for challenging targets. In October 2024, the company closed a €4.2 million seed funding round, bringing its total equity financing to €8.6 million. This investment supports their mission to revolutionize antibody design through generative AI.
