Adult isoantigen and lectin reactivity of bovine fetal red cells.
Evidence  is presented that fetal red cell membranes differ from membranes of their dams in isoantigenic and lectin reactivities. Evidence for nonsimultaneous development of 'adult' antigenic factors is extended. It is proposed that 'adult' phenogroups develop from replacement or displacement of factors in 'fetal' phenogroups.
