The lectins Ulex europaeus 1 (UEA 1), Ricinus communis 1 (RCA 1), Wheat Germ Agglutinin (WGA), and Lens culinaris agglutinin (LCA) which are specific for L-fucose, D-galactose, N-acetylglucosamine, and D-mannose respectively, have been used to localize cytochemically the presence of these sugar residues in certain human, mammalian, and amphibian cell types. Thin sections of Lowicryl K4M-embedded human distal colon, rat duodenum, and frog dorsal root ganglion were incubated with UEA 1-gold, RCA 1-gold, WGA/ovomucoid-gold, or LCA-gold. UEA-1, RCA-1, and LCA binding sites were present in the nuclei of human colonic cells, rat duodenal goblet and columnar cells and frog dorsal root ganglion neurons, satellite cells, and Schwann cells. Most of the nuclear binding sites were localized in the euchromatin compartment, while extranuclear labelling was largely restricted to sites known to contain glycoproteins. WGA binding sites were present in the nuclei of rat duodenum columnar cells and frog dorsal root ganglion neurons, satellite cells, and Schwann cells, but no labelling of human colonic cell nuclei was observed. Thus, we report the presence of these sugars in the nuceloplasm of human colonic cells (with the exception of WGA), rat duodenal villous columnar cells, and frog dorsal root ganglion cells examined.
