After 10 years of effort, H185 antibody was identified as a carbohydrate antigen on the membrane-associated mucin MUC16.42 The immunofluorescence micrographs of human corneal epithelium show colocalization of MUC16 and H185 antigen. This data and data showing co-immunoprecipitation of the same molecules with MUC16 and H185 antibodies demonstrate their identity. Bar = 25 μm.
