Histochemical study of the epithelia of nasal polyps by biotinylated lectins and neoglycoprotein. A comparison with the normal human respiratory epithelium.


Formalin-fixed, paraffin-embedded sections from human nasal polyps and the normal respiratory epithelium were glycohistochemically investigated. Three biotinylated lectins were used: peanut (Arachis hypogaea) agglutinin (PNA) which, binds to terminal galactose (beta 1-3) N-acetylgalactosamine residues that can be unmasked by a neuraminidase digestion; wheat… (More)
