About IRIG

Exploring the functions and potentials of chicken egg antibodies

For over 30 years, the Immunology Research Institute in Gifu (IRIG) has pioneered research on chicken egg antibody (IgY) technology. We have successfully developed many patented IgY applications against different pathogens in human, production animals, and pets.

What is IgY?
