The preparation, properties, and some applications of ferritin conjugates of two plant agglutinins, concanavalin A and Ricinus communis agglutinin, are reported. These conjugates serve as specific electron-dense stains for cell- and membrane-bound saccharide residues of the alpha-D-mannopyranosyl and beta-D-galactopyranosyl configurations, respectively, and as examples of a wide range of ferrit...

An inclusion complex consisting of a fluorescent phenylboronic acid (C1-APB) and beta-cyclodextrin (beta-CD) acts as a supramolecular saccharide sensor whose response mechanism is based on photoinduced electron transfer (PET). This study evaluated four kinds of cyclodextrins (alpha-CD, beta-CD, gamma-CD, and NH(2)-beta-CD) by comparing their pH profiles, and confirmed that beta-CD was the best ...

Previous studies with saccharide-protein conjugates have demonstrated that antibody responses to the saccharide can be improved by the preexistence of carrier immunity. Here we report that prior exposure to the carrier protein can either enhance or suppress antibody response to polysaccharides administered in saccharide-protein conjugates. A dose-dependent role for carrier priming in the antisa...

Saccharide oxyanions obtained by base treatment could be employed in glycosylation to give oligosaccharides with high stereo- and regioselectivities.

The purpose of this study was to detect saccharide-protein interaction capitalizing on the gel-modified field effect transistor [FET]. A lectin-sensitive polymer gel that undergoes volume changes in response to the formation of molecular complex between 'pendant' carbohydrate and a 'target' lectin concanavalin A [Con A] was synthesized. It was revealed that direction and magnitude of the gel re...

Saccharides on the cell surfaces play important roles in the living systems. For example, it mediate the cell-cell adhesion, fertilization, protein transportation, infection of pathogens and cancer metastasis etc [1, 2]. The saccharide-protein interactions also involve the various biological events (Table 1). Actualy, the saccharides are the model compounds of some of the medicines like oseltam...

Acid-catalyzed hydrolysis of glycosidic bonds is the most important degradation mechanism affecting cellulose-based materials. It results in decrease DP and loss original mechanical properties. The neutralization acidity therefore one efficient ways to hamper cellulosic artworks. However, case acidic strongly degraded artifacts, addition deacidification, a consolidation treatment must be perfor...
