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/Krak?w, Poland), were introduced.
