Lectin binding to bronchial epithelium using different detection methods. Serial sections for comparison of detection methods for lectin binding of Sambucus nigra agglutinin (SNA) to SAα2,6 and Maackia amurensis (MAA) agglutinin for binding to SAα2,3 in adult bronchial epithelium. Double fluoresecence for FITC labelled SNA and TRITC labelled MAA shows a heterogeneous pattern (A), with more binding to the basal epithelium with MAA (B) than SNA (C). HRP labelling of MAA (D) and SNA (E) shows a similar pattern of binding to the fluorescent labelled lectin. 200 × magnification.
