Mucin-specific lectin from Sambucus sieboldiana (SSA-M) reacts in Western blotting and ELISA with mucins from porcine stomach, bovine and ovine submaxillary glands, the human milk fat globule membrane, in vitro human ovarian, breast and colonic tumor cell lines, and mucins produced in vivo in the

A novel series of synthetic biantennary tri-, penta- and hepta-saccharides with terminal beta-GlcNAc, beta-LacNAc and alpha NeuAc(2,6)beta LacNAc residues, respectively, [LacNAc = Gal beta (1,4)Glc-NAc] connected to a core Gal residue were evaluated for their inhibitory potencies for specific plant

T cells from patients with systemic lupus erythematosus (SLE) show a decreased activation threshold and increased apoptosis. These processes seem to be regulated by glycosylated molecules on the T cell surface. Here, we determined through flow cytometry the expression of mucin-type O-glycans on T

Fruits of elderberry (Sambucus nigra) express small quantities of a type-2 ribosome-inactivating protein with an exclusive specificity towards the NeuAc(alpha2,6)Gal/GalNAc disaccharide and a unique molecular structure typified by the occurrence of a disulfide bridge between the B-chains of two

Fibromodulin from bovine articular cartilage has been subjected to lectin affinity chromatography by Sambucus nigra lectin which binds α(2-6)- linked N-acetylneuraminic acid, and the structure of the keratan sulphate in the binding and non-binding fractions examined by keratanase II digestion and

Rod and cone photoreceptors project from the outer retinal surface into a carbohydrate-rich interphotoreceptor matrix (IPM). Unique IPM glycoconjugates are distributed around rods and cones. Wheat germ agglutinin (WGA) strongly decorates the rod matrix domains and weakly decorates the cone matrix

A compact biosensor for a label-free, rapid (<80 s) detection of glycan-lectin interactions using ac impedance measurements was developed for the first time. A galactose-binding peanut agglutinin (PNA) and sialic acid-binding Sambucus nigra agglutinin (SNA) were covalently surface-immobilized on the

The sialic acid-specific leukoagglutinating lectin from the seeds of Maackia amurensis (MAL) has been studied by the techniques of quantitative precipitin formation, hapten inhibition of precipitation, hapten inhibition using an enzyme-linked immunosorbent assay, and lectin affinity chromatography.

A lectin (agglutinin) from fresh fruit bodies of the brown roll-rim fungus [Paxillus involutus (Fr.) Fr.] has been purified with output approx. 60 mg÷kg of raw material. Method of purification included the sedimentation of viscous polysaccharide by ethanol, removal of ethanol by dialysis,

A second lectin (SNA-II) has been isolated from elderberry (Sambucus nigra L.) bark by affinity chromatography on immobilized asialo-glycophorin. This lectin is a blood group nonspecific glycoprotein containing 7.8% carbohydrate and which is rich in asparagine/aspartic acid, glutamine/glutamic acid,

The binding of L-selectin to the HEV-derived ligand GlyCAM-1 bears a strict requirement for oligosaccharide sulfation. In the companion study [Hemmerich, S., Bertozzi, C.R., Leffler, H., & Rosen, S. D. (1994) Biochemistry 33, 4820-4829], we identified the major sulfated mono- and disaccharides of

The ability of human spermatozoa recovered from highly motile sperm fractions to bind wheat germ agglutinin (WGA) after discontinuous Percoll gradient centrifugation was studied. WGA could bind to almost all motile spermatozoa, whereas fewer than 25% of spermatozoa could bind peanut (PNA) and

In the thymus, glycosylation status of many cell surface molecules changes during the thymocyte maturation and selection processes. In this study, we evaluated the glycosylation changes and possible relationships with programmed cell death in the thymic tissues from mouse embryos at the days 14

Sialic acids of glycoconjugates play crucial roles in various biological processes, such as cell-cell communication and cell-substrate interaction. A sisalyltransferase, ST6GalNAc IV (Neu5Ac-alpha2,3-Gal-beta1,3-GalNAc-alpha2,6-sialyltransferase), catalyzes the formation of alpha2-6-linkages onto

A series of spacer-N-linked glycopolymers carrying long/short α2,3/6 sialylated glycan were designed as polymeric inhibitors of influenza virus. Lactose (Lac) and N-acetyllactosamine (LN: Galβ1,4GlcNAc) were first converted to spacer-N-linked disaccharide glycosides, followed by consecutive
