The interaction of concanavalin A with blood-group-substance glycoproteins from human secretions.
1. Gastric juice, saliva and ovarian-cyst fluid were fractionated into glycoprotein components by centrifuging to equilibrium in a caesium chloride density gradient. 2. The glycoprotein fractions from the gastric juice of two group O non-secretors, two group O secretors and three group A secretors all formed insoluble complexes with concanavalin A. 3. Fractions showing maximum interaction with ...
متن کاملSurface Glycoproteins of Human White Blood Cells
We labeled surface glycoproteins of norby polyacrylamide slab gel electrophoresis. mal human blood platelets, granulocytes, All major types of human leukocytes monocytes, T and B lymphocytes, and null showed different and characteristic surcells by the galactose oxidase-NaB3H4 face glycoprotein patterns. These patterns and periodate-NaB3H4 labeling techevidently also include common comniques. T...
متن کاملLaminin-10 and Lutheran blood group glycoproteins in adhesion of human endothelial cells.
Laminin alpha5-chain, a constituent of laminins-10 and -11, is expressed in endothelial basement membranes. In this study we evaluated the roles of alpha5 laminins and Lutheran blood group glycoproteins (Lu), recently identified receptors of the laminin alpha5-chain, in the adhesion of human dermal microvascular and pulmonary artery endothelial cells. Field emission scanning electron microscopy...
متن کاملIdentification of glycoproteins bearing human blood group in rabbit enterocyte plasma membranes
The presence or absence of human blood group A-like substances in the intestinal secretions of animals has enabled them to be classified as A+ and A-, respectively [ 1,2]. This A antigenicity is due to the terminal trisaccharide cw-GalNAc-[a -Fuc(1_2)]P -Galof O-linked glycans of glycoproteins [3]. The surface of intestinal absorbing cells or enterocytes in A+ rabbits also bears the A antigenit...
متن کاملStructural analysis of the Ss sialoglycoprotein specific for Henshaw blood group from human erythrocyte membranes.
The N-terminal structures of the MN and Ss erythrocyte membrane sialoglycoproteins (glycophorins A, B) from two Henshaw (He) blood-group heterozygotes were determined by manual sequencing of tryptic glycopeptides and various secondary fragments. No structural alteration of the MN glycoprotein could be detected. The He-specific portion of the Ss glycoprotein was found to exhibit the N-terminal s...
