title: Lack of blood group antigen A on human corneal endothelium.
abstract: Using direct immunofluorescence and mixed agglutination, we did not find blood group antigen A on human corneal endothelium from patients of blood type A or AB. The antigen was easily detected on the epithelium of these patients. We believe that the ABO blood group antigens are probably absent on human corneal endothelium, therefore they cannot play a direct role in specific corneal endothelial rejection.
