dc.description.abstract | The lectin from the mushroom Polysporus squamosus (PSL) has an extended carbohydrate combining site, which exhibits a high specificity and affinity toward the NeuAc5α2,6Galβ1,4Glc/GlcNAc trisaccharide sequence of asparagine-linked oligosaccharides. Therefore, PSL should be a superior reagent to the lectin from Sambucus nigra (SNA), which does not discriminate between α2,6-linked NeuAc5 present either in asparagine- or serine/threonine-linked oligosaccharides. We have prepared a digoxigenin-conjugated PSL and applied it for histochemistry and blotting. We observed a more restricted staining pattern by PSL as compared to SNA in paraffin sections from different rat organs. Pretreatment of sections with N -glycanase F abolished PSL staining indicating that it interacts only with asparagine-linked oligosaccharides. Furthermore, PSL staining was neuraminidase sensitive. In contrast, SNA staining was only partially sensitive to N -glycanase F pretreatment demonstrating that it was in part due to α2,6-linked NeuAc5 present in serine/threonine-linked oligosaccharides. The most striking observation in this regard was that PSL, in contrast to SNA, did not stain the mucus of sheep submandibular gland, which is extremely rich in serine/threonine-linked Neu5Acα2,6 N -acetylgalactosamine. Furthermore, in some tissues neuraminidase pretreatment resulted in increased intensity of SNA staining probably due to binding to exposed terminal N -acetylgalactosamine residues. Collectively, these results indicate that PSL is a useful tool for the histochemical detection of α2,6-linked NeuAc5 in asparagine-linked oligosaccharides. | en_US |
