Use was made of seven FITC labelled lectins as tools to investigate the surface of Onchocerca lienalis larvae as they develop through to the infective third-stage in a natural vector, Simulium ornatum. The lectins were derived from Canavalia ensiformis (Con A), Lens culinaris (lentil), Triticum

Lectins labeled with 125I or conjugated with fluorescein were employed to study the carbohydrates on the surface of different stages of schistosomula of Schistosoma mansoni. Newly transformed schistosomula were shown to bind concanavalin A; the 60 000 and 120 000 dalton agglutinins from Ricinus

The surface architecture of adult male Schistosoma mansoni was explored using a range of lectins with differing carbohydrate specificites. Highest specific binding was achieved with concanavalin A and the agglutinin of molecular weight 60000 from Ricinus communis; the binding of wheat germ

Fluorescent conjugates of the lectins soybean agglutinin (SBA), Concanavalin A (Con A), wheat germ agglutinin (WGA), Lotus tetragonolobus agglutinin (LOT), and Limulus polyphemus agglutinin (LPA) bound primarily to amphidial openings and amphidial secretions of viable, preinfective second-stage

The composition of carbohydrates on the surface of platelets from a patient with Glanzmann's thrombasthenia and from seven normal donors were determined and compared. To this end, binding studies were performed using nine different purified 125I-labeled lectins; Concanavalin A,

Lectins react with a wide range of different carbohydrates (Table 1). Even so-called monospecific anti-H(O) lectins from Lotus tetragonolobus, Ulex europaeus, and Anguilla anguilla react not only with the anti-H determinant but also with several fucosylated carbohydrates. Consequently, the type of

The cell surface carbohydrates of Leishmania mexicana amazonensis (amastigotes and promastigotes, both infective and non-infective forms) were comparatively analyzed by agglutination assay employing 28 highly purified lectins, and by binding assay using 125I-labeled lectins. Among the D-GalNAc

Vinorama isolectins (VL2-VL4) were purified from seeds of Acacia constricta (vinorama) using affinity chromatography on a fetuin-fractogel column followed by cationic-exchange chromatography. Each isolectin fraction presented a characteristic isoelectric point range from 5.5 to 8.4. Under native

The turkey sperm glycocalyx is known to contain residues of sialic acid, alpha-mannose/alpha-glucose, alpha- and beta-galactose, alpha-fucose, alpha- and beta-N-acetyl-galactosamine, monomers and dimers of N-acetyl-glucosamine, and N-acetyl-lactosamine. Potential changes in these carbohydrates

BACKGROUND The carbohydrates of gastric mucins and other sugar structures are involved in interactions with Helicobacter pylori (H. pylori) adhesins. The binding of bacteria to mucins can protect the epithelium from direct contact with the pathogen and from developing infection because of a specific

In the present investigation, we examined the role of trophoblast and parietal endoderm cells in the synthesis of carbohydrate-containing components of Reichert's membrane. To eliminate the function of Reichert's membrane as a filter between maternal and embryonal tissues we carried out our

This study was conducted to examine the lymph node metastasis-related carbohydrate epitopes of cancer cells in primary lesions of gastric cancer with submucosal invasion (sm gastric cancer). A total of 118 formalin-fixed and paraffin-embedded surgical specimens were studied. Carbohydrate epitopes

Cancer sera have high levels of an abnormal form of haptoglobin (Hp) that can be extracted from blood using the fucose-specific lectin, Lotus tetragonolobus. In order to investigate the carbohydrate abnormality that is responsible for this effect, the monosaccharide composition of Hp has been

Peptide fragments have been obtained from L-fucose-binding anti-H(O) lectins [Lotus tetragonolobus lectin (LTA) and Ulex europeus lectin I (UEA-I)] and di-N-acetylchitobiose-binding anti-H(O) lectins [Ulex europeus lectin II (UEA-II) and Laburnum alpinum lectin I (LAA-I)] by treatment with

The purification of rat liver beta-glucuronidase from a lysosomal fraction by methods including affinity chromatography, chromatofocusing and preparative PAGE steps is described. Molecular weights of 300,000 and 150,000 were estimated by two dimensional gradient PAGE/immunoelectrophoresis of the
