background: major histocompatibility complex (mhc) plays a central role in regulation and control of the immune responses to infectious diseases. due to its polymorphism, individual differences in response to vaccines have been observed in different chicken populations. studying the association of chicken mhc with immune response to vaccines will help the control of infectious disease and vacci...

According to Linscott"s Directory of Immunological and Biological Reagents (1994/95) the commercial availability of egg-yolk antibodies (IgY) is extremely low. For preparation, cleaning and detection of IgY it would be of advantage to have a "Protein Y" available analogous to protein A and protein G for mammalian antibodies. Until now, the search for "Protein Y" was unsuccessful. IgY has been u...
