IgY Lab Systems

IgY Lab Systems is a Swedish biotechnology company specializing in the production and purification of polyclonal chicken antibodies, known as Immunoglobulin Y (IgY). Based in the life science hub of Uppsala, the company provides custom antibody services to the global research and diagnostic communities. Their core expertise lies in utilizing the avian immune system to generate antibodies against highly conserved mammalian proteins that are often poorly immunogenic in traditional mammalian hosts like rabbits or mice. IgY Lab Systems offers a comprehensive workflow including antigen design, hen immunization, and proprietary purification methods to extract high-purity antibodies from egg yolks. These avian antibodies provide distinct advantages, such as the lack of cross-reactivity with rheumatoid factors and the human complement system, making them valuable tools in clinical diagnostics and research.
