The results of previous research on antigenic (allotypic) specificities of immunoglobulins, alpha-globulins, beta-globulins and lipoproteins in cattle are reviewed. The suitability of heteroantibodies and alloantibodies for identification of this type of markers was analysed. New names/symbols of antigenic markers of proteins in cattle, identified at the Department of Immuno- and Cytogenetics of the National Research Institute of Animal Production (Balice/Kraków, Poland), were introduced.
