The circular dichroism (CD) spectra of thirteen lectins, most being specific for D-galactose or N-acetyl-D-galactosamine, were compared. Two groupings are proposed on the basis of the CD in the near-ultraviolet region. Group one comprises the lectins from Arachis hypogaea, Glycine max, Phaseolus
In this study, lectin histochemistry was performed on paraffin sections to compare carbohydrate expression of oviductal isthmus and uterine endometrium in rabbits during early embryo development. Rabbit embryos are surrounded not only by the zona pellucida but also by tubal secretion-derived
Binding patterns of fluorescein isothiocyanate (FITC)- and gold-conjugated lectins to extracellularly melanized sheathed and exsheathed microfilariae of subperiodic Brugia malayi, isolated from and in situ in the abdominal hemocoel of Anopheles quadrimaculatus 72-hr postinfection, were examined.
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
The viviparous shark Mustelus canis nurtures its young within the uterus by means of a modified yolk sac which functions as a placenta. Two term specimens have been examined with a panel of 21 biotinylated lectins to assess whether glycans form a prominent interface between fetal and maternal
The aim of the present study was to investigate the distribution of the glycoconjugates sialoderivatives in the human testis. Orchidectomy specimens from men aged 18-30 years (Group 1) and from men aged 70-93 years (Group 2) were obtained at autopsy. The study was performed using
T- and T-like antigens on glycoproteins and glycolipids were examined in extracts of human urinary bladder tumors and normal tissue by Western blot analysis and reagent binding to thin layer chromatograms. Three different anti-T-reagents were used: peanut (Arachis hypogaea) lectin (PNA) and mono-
Anti-TF agglutinins from peanut (Arachis hypogaea) and from vertebrate sera of different species have been successfully isolated by affinity chromatography on acid-activated Sepharose 4 B. The proteins were characterized by immunoelectrophoresis, polyacrylamide gel electrophoresis in the presence of
Hyphomonas strain MHS-3 (MHS-3) is a marine procaryote with a biphasic life cycle and which has prosthecate stages that adhere to submerged substrata. We found that adherent forms produced an exopolysaccharide (EPS) capsule that bound Glycine max lectin, Arachis hypogaea lectin, and Bauhinia
OBJECTIVE
Histiotrophe is now recognized as being an important feature of early human pregnancy, providing nutrients and growth factors to the developing embryo. Our aim was to examine the glycan composition of histiotrophe from first trimester decidua and to compare it with secretions present in
The binding of fluorescein isothiocyanate (FITC)-conjugated lectins to mucin in the human colon was studied by using fluorescence microscopy. In normal mucosa, lectins that preferentially bind to exposed N-acetyl-galactosamine residues (Dolichos biflorus agglutinin and soybean agglutinin) bound
In the present study carbohydrate residues in taste buds (TBs) and adjacent epithelial formations of a teleostean fish, a frog and the rabbit were detected by means of lectin histochemistry. Biotinylated lectins from Pisum sativum (PSA), Arachis hypogaea (PNA), Dolichos biflorus (DBA), Triticum
Mucous cells and enteroendocrine cells of the pyloric region of the ruin lizard (Podarcis sicula campestris De Betta) have been examined by lectin histochemical and immunohistochemical methods. Binding to five plant lectins (Canavalia ensiformis, Con A; Triticum vulgare, wheat germ, WGL; Lotus
Distribution of lectin binding in the testis of the musk shrew, Suncus murinus, was investigated by light and transmission electron microscopy. Not only spermatogenic cells but also Sertoli cells bound some lectins. Canavalia ensiformis agglutinin (Con A) and wheat germ agglutinin (WGA, Triticum
The cells of Actinomyces viscosus ATCC 19246 (Av19246) and Streptococcus sanguis ATCC 10557 (Ss10557) coaggregated immediately after mixing in 40 mM-Tris/HCl buffer. Optimal conditions were pH 7.5 in the presence of Ca2+ at 0.1 mM or higher. Na2 EDTA and its analogues, Na2MgEDTA and Na2MnEDTA at 7.5
