Characterization of N-linked oligosaccharides assembled on secretory recombinant glucose oxidase and cell wall mannoproteins from the methylotrophic yeast Hansenula polymorpha.

abstract：:Glycosaminoglycans (GAGs) are long, anionic polysaccharides involved in many basic aspects of mammalian physiology and pathology. Here we describe a method to extract GAGs from formalin-fixed, paraffin-embedded tissues and found that they are structurally comparable with GAGs extracted from frozen tissues. We employed...

abstract：:Galactans are linear polysaccharides of β(1→4)-linked galactose residues. Although they can antagonize galectin function, the nature of their binding to galectins needs to be better defined to develop them as drugs. Here, we investigated interactions between galectin-3 (Gal-3) and a series of galactans ranging in weig...
