An anti-mesothelial monoclonal antibody that recognizes an unknown antigen on the microvilli of mesothelioma cells by staining normal mesothelial cells as well as epithelial mesotheliomas in a thick membrane pattern. It has also been found to be useful as part of a panel of markers in the distinction of thyroid carcinomas from adenomas and reacts with some carcinomas showing cytoplasmic immunostaining.
