“…RCA-1: Paget cells displayed very weak staining, and squamous cells slight to Identification of sugar residues in cellular macromolecules was applied with use of the lectin binding site as a specific marker for detecting sugar residues (9,23,26). Recently, lectin binding sites or binding affinities in varying types: of the skin and mucosal lesions have been described as well as in normal squamous cell epithelia (3,7,11,(15)(16)(17)(18)24) . In malignantly transformed epithelia, lectin binding patterns displayed a change to irregular distribution with reduced stainability (15)(16)(17).…”
