hemagglutinin

(hē′mə-glo͞ot′n-ĭn)
n.
A substance that causes agglutination of red blood cells, such as an antibody, or a glycoprotein found on the surface of a virus. Viral hemagglutinins enable viruses to bind to host cells.

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 xenogeneic (from an organism of a different species).
