Welcome to the website of Immunology Research Institute in Gifu (IRIG).
For many years IRIG has been focusing on both basic and application research on IgY.
As a result, various IgY products have been used as functional ingredients in foods for humans
as well as in feeds for domesticated animals and pets. This website introduces recent research
projects conducted by IRIG on IgY and its application.
