Tissue binding of Maackia amurensis agglutinin I (A), Maackia amurensis agglutinin II (B) and Sambucus nigra agglutinin (C) in the porcine olfactory part of the nasal mucosa. Siaα2,3‐galactoseβ1,4‐glucosamine (A) was abundantly expressed on the epithelial lining, Siaα2,3‐galactoseβ1,3‐glucosamine (B) moderately (indicated by the arrows). Sia α2,6‐galactose (C) was not detected in any of the epithelial cell layers.
