hemagglutinin
Etymology: Gk, haima + L, agglutinare
a type of antibody that agglutinates red blood cells. It is classified according to the source of cells agglutinated as autologous (from the same organism), homologous (from an organism of the same species), and xenogenic (from an organism of a different species). Some hemagglutinins clump red cells together as they are suspended in 0.85% sodium chloride solution; others will not agglutinate red cells unless hydrophilic colloids are added or unless the red cells have been treated with a proteolytic enzyme.
