摘　　要：The term“IgY technology”was introduced in the literature in the mid 1990s to describe a procedure involving immunization of avian species,mainly laying hens and consequent isolation of the polyclonal IgYs from the“immune”egg yolk(thus avoiding bleeding and animal stress).IgYs have been applied to various fields of medicine and biotechnology.The present article will deal with specific aspects of IgY technology,focusing on the currently reported methods for developing,isolating,evaluating and storing polyclonal IgYs.Other topics such as current information on isolation protocols or evaluation of IgYs from different avian species are also discussed.Specific advantages of IgY technology(e.g.,novel antibody specificities that may emerge via the avian immune system)will also be discussed.Recent in vitro applications of polyclonal egg yolk-derived IgYs to the field of disease diagnosis in human and veterinary medicine through in vitro immunodetection of target biomolecules will be presented.Moreover,ethical aspects associated with animal well-being as well as new promising approaches that are relevant to the original IgY technology(e.g.,development of monoclonal IgYs and IgY-like antibodies through the phage display technique or in transgenic chickens)and future prospects in the area will also be mentioned.
