neuraminic acid/arachis hypogaea

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

Hemolytic-uremic syndrome (HUS) accompanied by pneumococcal infections forms a characteristic subgroup of HUS. Pneumococcal neuraminidase splits off neuraminic acid from the glycoproteins present on the surface of red cells, thrombocytes and endothelial cells, and thus exposes the hidden Thomsen

The granular cell tumourettes of the posterior lobe of the pituitary possess neuraminic acid containing carbohydrate. After removal of neuraminic acid with neuraminidase and exposure to FITC (Fluorescein isothiocyanate) labelled peanut agglutinin (Arachis hypogaea) (PNA), intracellular receptor

Human serum glycoproteins can be classified into those containing N-acetyl-D-galactosamine and into those lacking this hexosamine. The N-acetyl-D-galactosamine-containing serum glycoproteins have alkali-labile chains containing this hexosamine linked O-glycosidically to hydroxy amino acids. These

Lectins were used to characterize bone forming cells in posttraumatic myositis ossificans. The lectins applied were as follows: Arachis hypogaea (PNA): specific for beta-D-galactose (1,3)N-acetyl-D-galactosamine (Gal-1,3 GalNac), Canavalia ensiformis (Con A): specific for alpha-D-glucose (D-Glc) and

A procedure for the determination of activity and linkage specificity of sialidases is described. The sialoglycoprotein fetuin is coated onto a microtiter plate and incubated with sialidases from different sources. Enzymatic activities and linkage specificities are then determined by a sandwich

A disease of the nervous system is reported in goats in the semiarid region of northeastern Brazil. Histological examination showed diffuse vacuolation of neurons and epithelial cells of the pancreas, thyroid, renal tubules, and liver. The swainsonine-containing plant Ipomoea verbascoidea was found

Arachis hypogaea (PNA) lectin, specific for Gal-B-1,3-GalNac disaccharide and Wheat germ (WGA) lectin, specific for (GlcNac) and terminal neuraminic acid were used to identify histiocytic giant cells, osteoclast like giant cells and osteoclasts. PNA lectin, without neuraminidase predigestion was not

The epithelium at the trigone of the urinary bladder showed intestinal metaplasia of a colonic type in three Holstein-Friesian cows affected with chronic polypoid cystitis. Except for Ricinus communis (RCA-I), almost all goblet cells in the whole crypt were positive to periodic acid-Schiff (PAS),

The gerbils brains after 3- and 4-minute-long ischemia caused by bilateral common carotid artery occlusion and 14 days survival were investigated using lectin techniques. Chosen lectins, represented by synthetic plant glycoproteids, which are specifically bound to particular sugar residues
