Glycoproteins histochemistry of the gills of Odontesthes bonariensis (Teleostei, Atherinopsidae)

Journal of Fish Biology, 2010
The histochemistry of glycoproteins (GP) in the mucous cells of the gills of the silverside Odontesthes bonariensis was identified with: (1) oxidizable vicinal diols; (2) sialic acid and some of their chain variants, carbon 7 (7C), carbon 8 (8C) or carbon 9 (9C); (3) sialic acid residues without O‐acyl substitution and with O‐acyl substitution at 7C ...
