Selective presence of SAα2,3Gal (MAAI, MAAII lectin) and SAα2,6Gal (SNA lectin) receptors in different pika organs. (A) Expression of SAα2,3Gal (red) and SAα2,6Gal (green) receptors was detected by MAAI and SNA lectin staining in contrast to nuclear staining (blue) with DAPI and presented as composite confocal images in many pika organs including the trachea (a), lung (b), duodenum (c), ileum (d), rectum (e), kidney (f), brain (g), liver (h), heart (i), and spleen (j) as indicated above. Bar, 100 μm. (B) Expression of SAα2, 3Gal (red) receptors was revealed by MAAII staining relative to nuclear staining (blue) with DAPI. The organs are labeled as in Figure 1A. Bar, 100 μm.
