The Use of Avian Yolk Antibodies in Biomedical Research

The document discusses the use of avian yolk antibodies (IgY) in biomedical research, highlighting their potential in passive immunization, a concept initially proposed by E. Behring. IgY antibodies, derived from the egg yolks of immunized birds such as chickens, quails, and ducks, offer a non-invasive and ethical alternative to mammalian antibodies. The technology has gained significant interest over the past decade due to advancements in laboratory techniques, leading to its industrial production and commercialization. IgY antibodies are being developed against various pathogens responsible for diseases like dental caries and peptic ulcers, offering a promising avenue for therapy and disease prevention without the side effects associated with mammalian antibodies. Despite its potential, IgY technology remains underappreciated in some regions, such as Russia.
