Mass spectrometric analysis of chitooligosaccharides and their interaction with proteins
Chitooligosaccharides are composed of glycosamin and N-acetylglycisamin residues. Gel permeations chromatography is employed for the separation of oligomers, cation exchange chromatography is used for the separation of homologes and isomers. Trideuterioacetylation of the chitooligosaccharides …

Production and characterization of the recombinant wheat chitinase Wch1 and generation of chitin-specific antibodies
… assay allowing simple and rapid detection of chitooligosaccharides released from the degradation of chitin substrate in a fermenter. This assay would constitute a valuable tool for monitoring as well as quality assessment of the oligomers throughout the of the production process. The strategy …

Synthesis of Hetero-chitooligosaccharides
Chitooligosaccharides are composed of linear β-(1→4)-linked 2-acetamido-2-deoxy-β-D-glucopyranose (GlcNAc) and/or 2-amino-2-deoxy-β-D-glucopyranose (GlcN). They are of interest due to their remarkable biological properties including antibacterial, antitumor, antifungal and elicitor activities. They …

Solution and solid phase synthesis of N,N'-diacetyl chitotetraoses
… of GlcN and GlcNAc) occurs in certain fungi. Chitooligosaccharides of mixed acetylation patterns are of interest for the determination of the substrate specificities and mechanism of chitinases. In this report, we describe the chemical synthesis of three chitotetraoses namely …
