The lectin binding characteristics of goldfish retinal explants were examined by fluorescence microscopy. Neurites grown out from cultured retinal explants were found to bind concanavalin A, wheat germ agglutinin and ricin (agglutinin). The effects of tissue fixation on lectin binding to retinal explant neurites suggest that glycolipids may constitute the predominant ricin binding sites. A redu...
In W303-derived strains, disruption of FIG2 increased agglutinability of alpha cells, but not a cells, and did not alter expression of alpha-agglutinin, binding of 125I-labeled alpha-agglutinin, or mating efficiency. Fig2p overexpression led to alpha-cell-specfic suppression of agglutinability. These results imply that Fig2p is an indirect masker of the active sites in alpha-agglutinin.
Salivary agglutinin is a high molecular mass component of human saliva that binds Streptococcus mutans, an oral bacterium implicated in dental caries. To study its protein sequence, we isolated the agglutinin from human parotid saliva. After trypsin digestion, a portion was analyzed by matrix-assisted laser/desorption ionization time-of-flight mass spectrometry (MALDI-TOF MS), which gave the mo...
hemagglutination activity (enhanced lectin activity) not expressed by nonactivated platelets, and this agglutinin mediates the direct platelet-platelet interactions that cause the aggregation of thrombinactivated platelets. The enhanced agglutinin activity of thrombin-activated platelets is composed of two components: a plasma membrane-bound component and a soluble component.3 The expression of...
Purpose: Plasma membrane glycoconjugates are important determinantsof differentiation and iteraction during spermtogenesis. Which entails miotic and meiosis proliferation, alternation in cell shape and so on. Hihg rates of them synthetized and present in acrosomes. With attention to such importancy, the present study has was designed to analyze glycoconjugates with special terminal sugar residu...
The olfactory and respiratory mucosae of the Corriedale sheep were examined using lectin histochemistry in order to clarify the histochemical and glycohistochemical differences between these two tissues. The olfactory epithelium was stained with 13 lectins out of 21 lectins examined, while the respiratory epithelium was positive to 16 lectins. The free border of both of the olfactory and respir...
A new methodology was developed to study the cell-surface glycoproteins of cultured human skin fibroblasts. This was based on the binding of a variety of biotinyl-lectins to nitrocellulose electrophoretic transfers of total fibroblast lysates after separation in sodium dodecyl sulphate/polyacrylamide gels, followed by reaction with avidin-biotinyl-peroxidase complexes and detection with 3,3'-di...
The interaction between a surface protein antigen (PAc) of Streptococcus mutans and human salivary agglutinin was analyzed with a surface plasmon resonance biosensor. The major component sugars of the salivary agglutinin were galactose, fucose, mannose, N-acetylglucosamine, N-acetylgalactosamine, and N-acetylneuraminic acid. Binding of salivary agglutinin to PAc was calcium dependent and heat l...
