Figure 4From: Sialic acid receptor detection in the human respiratory tract: evidence for widespread distribution of potential binding sites for human and avian influenza virusesComparison of MAA binding using MAA from different suppliers. Serial sections of adult lung tissue for comparison of lectin binding of Maackia amurensis (MAA) for SAα2,3Gal. Biotin conjugated MAA1(also known as MAL) from Vector Laboratories (A) and (E), Biotin conjugated MAA2 (also known as MAH) from Vector Laboratories (B) and (F), Digoxigenin conjugated MAA from Roche (C) and (G) and HRP conjugated MAA from EY Laboratories (D) and (H). Orange arrows indicate alveolar macrophages, Green arrows indicate alveolar pneumocytes and blue arrows indicate bronchiolar epithelium.
