title: Light-microscopic examination of ABH and Lewis antigens in human tracheal and epiglottic glands using the avidin-biotin-peroxidase complex technique.
abstract: The localization of ABH and Lewis antigens was examined in formalin-fixed, paraffin-embedded human tracheal and epiglottic glands using monoclonal anti A, B, H, Lea and Leb antibodies. The mucous cells of the glands showed reactivity with antibodies corresponding to the respective ABO blood groups of the tissue donors. The mucous cells from one blood group A, Le(a-b-) individual showed no reactivity with any antibodies and those from another blood group A, Le(a-b-) individual showed reactivity only with anti A antibody. In individuals from blood group Le(a + b-) of all ABO groups, the mucous cells reacted exclusively with anti Lea. In blood group O, Le(a-b+) individuals, the mucous cells showed intense reaction with anti H and Leb antibodies and weak to moderate reactivity with anti Lea. In Le(a-b+) individuals of A1, B and A1B blood groups, the mucous cells showed strong reactivity with anti A and/or B antibodies, moderate with anti Leb, weak or no activity with anti Lea and absent with anti H. In blood group A2 Le(a-b+) individuals, the mucous cells stained with anti A were weakly stained or completely unstained with anti H antibody, but cells negative with anti A gave strong positive reactions with anti H antibody.
