The agglutination responses of three Drosophila cell lines to concanavalin A and wheat germ agglutinin have been examined. Although the cell lines were originally derived from late embryonic stages of the Ore-R strain of Drosophila melanogaster. they show quantitative differences in lectininduced agglutination. Line 1 cells were least agglutinable with both lectins. All three cdl lines reached ...
Fifteen monoclonal antibodies (MAbs) raised against human sperm cells were evaluated for reactions against human sperm by indirect immunofluorescence, immunocytochemistry, agglutination, complement-dependent immobilization, cervical mucus penetration, and hamster egg penetration assays. The MAbs were analyzed for specificity by immunofluorescent reactions with peripheral blood lymphocytes and s...
Forty-six cultures of Listeria monocytogenes (including clinical, food and collection strains) were serotyped, characterized for motility, haemolysis and phospholipase activities and tested for lectin agglutination using a four-lectin set. Lectin reactivity (i.e. agglutination by one or more of the four lectins) was observed in all 12 clinical isolates, 16 of the 23 food isolates and eight of t...
Sperm sorting by flow cytometry is a useful technology in the bovine industry, but the conception rates after artificial insemination using sex-sorted sperm are lower than when using the un-sorted sperm. In this study, we have investigated the causes for these low conception rates. We have focused on changes caused by flow cytometry to the glycocalyx, which forms the outermost surface of the sp...
Lectins/carbohydrate binding can be involved in the Schistosoma mansoni recognition and activation of the Biomphalaria hemocytes. Therefore, expression of lectin ligands on Biomphalaria hemocytes would be associated with snail resistance against S. mansoni infection. To test this hypothesis, circulating hemocytes were isolated from B. glabrata BH (snail strain highy susceptible to S. mansoni), ...
A chemoattractant lectin from the dorsal spines of the redfin velvetfish, Hypodytes rubripinnis, was isolated using a combination of affinity chromatography techniques. The glycoprotein, with a molecular mass of 110 kDa, is named Karatoxin. Karatoxin caused agglutination of rabbit erythrocytes. This agglutination was effectively inhibited by D-mannose. In addition, Karatoxin exhibited not only ...
The existence of beta-lectins on protoplast surfaces is confirmed by the agglutination of protoplasts by those Yariv antigens that have sugar specificities which also interact with isolated beta-lectins. Agglutination by beta-maltosyl but not by beta-D-mannosyl Yariv antigens is used to identify some of the structural features required of the ligand for beta-lectin binding. Inhibition of agglut...
Lectins are carbohydrate-binding proteins with agglutination properties. There is a continuous interest in lectins due to their biological properties that can be exploited for medicinal and therapeutic purposes. The objective of this study was to isolate and characterize lectin activity in Texas Live Oak (Quercus fusiformis). More specifically, the study aimed to determine the lectin’s blood gr...
Cyclodextrin vesicles are versatile models for biological cell membranes since they provide a bilayer membrane that can easily be modified by host-guest interactions with functional guest molecules. In this article, we investigate the multivalent interaction of the lectin concanavalin A (ConA) with cyclodextrin vesicles decorated with mannose-adamantane conjugates with one, two or three adamant...
Antisperm antibodies were assessed in the serum samples of 73 men unable to ejaculate naturally and on the sperm cells of 13 of these men. None of the serum samples were found to be positive by sperm agglutination or sperm immobilization methods and antibodies were detected by an immunobead assay on the sperm cells of one of the 13 men examined.
