Development of IgY Technology: A Historical Perspective

IgY Technology is a scientific field classically related to the generation, evaluation and use of avian egg yolk IgY antibodies to develop biomedical and biotechnological solutions and applications. The field is more than 120 years old. However, in the last decades, major advances in research and development areas such as Genetics, Biochemistry, Bioengineering and Bioprocessing, have prompted new approaches to this old technology. In this chapter, a retrospective summary is given on the major milestones, key events and developments of IgY technology. We also bring an overview of the main topics and themes gathered and further developed within this book edition. The discussion on the perspective and future trend analysis of IgY technology is given in Chap. 18.
