Identification and Analysis of O-Acetylated Sialoglycoproteins
20125-N-acetylneuraminic acid, commonly known as sialic acid (Sia), constitutes a family of N- and O-substituted 9-carbon monosaccharides. Frequent modification of O-acetylations at positions C-7, C-8, or C-9 of Sias generates a family of O-acetylated sialic acid (O-AcSia) and plays crucial roles in many cellular events like cell-cell adhesion ...

Heterogeneity of the sialoglycoproteins of the normal human erythrocyte membrane
Biochemical and Biophysical Research Communications, 1976Abstract The sialoglycoproteins of the human erythrocyte membrane can be separated into at least eight periodic acid Schiff-positive components using sodium dodecyl sulfate gel electrophoresis in the discontinuous buffer system of Laemmli. All eight components can also be labeled by mild periodate oxidation followed by reduction with NaB 3 H 4 ...

Heterogeneity of human red cell membrane sialoglycoproteins
Blut, 1976Discontinuous sodium dodecysulfate polyacrylamide gel electrophoresis (disc SDS-PAGE) followed by periodic acid/Schiff staining reveals the presence of six sialoglycoprotein bands in human red cell membranes or glycoprotein preparations therefrom. In agreement with previous investigations it is shown that PAS-1 and PAS-2 (mol.

Gangliosides, sialoglycoproteins and acetylcholinesterase of the developing mouse brain
Wilhelm Roux's Archives of Developmental Biology, 1977The developmental accretion of up to nine individual gangliosides in foetal brains, peri- and postnatal cortices, postnatal cerebelli and olfactory lobes and in the liver and the spleen were investigated in mice and compared with that of glycoprotein-bound sialic acid and the activity of the acetylcholinesterase.In foetal brain and in postnatal liver ...

Interaction of Mistletoe Toxic Lectin-I with Sialoglycoproteins
Biochemical and Biophysical Research Communications, 1995The binding properties of mistletoe toxic lectin-I (ML-I) with sialo-N- and O-glycans were investigated by quantitative precipitin and precipitin inhibition assays. Human alpha 1-acid glycoprotein reacted strongly with ML-I, precipitating over 82% of the lectin nitrogen tested, while the precipitability of its asialo product decreased by 30%.

Cross-linking sialoglycoproteins of human erythrocyte membranes
Biochemical and Biophysical Research Communications, 1973Abstract Human erythrocyte ghosts were treated with a bifunctional cross-linking reagent, dimethyl adipimidate dihydrochloride. On SDS-polyacrylamide electrophoresis of the cross-linked membrane proteins after solubilization, sialoglycoproteins and the proteins disappeared from the original band positions and appeared in a new band of aggregates.

Sialoglycoproteins and filtration barriers in the glomerular capillary wall
Journal of Ultrastructure Research, 1975The free surface coat on foot processes of rat glomerular epithelium stains particularly heavily with ruthenium red and osmium tetroxide, indicating a polyanionic sialoglycoprotein. It is compressible and expansile, containing densely packed filaments 12–25 wide.

An antibody that recognizes a determinant common to S and s‐bearing sialoglycoproteins
Transfusion, 1982We describe an antibody, made by an individual of the phenotype M+, N+, S+, s+, U+, that reacted only with ficin or papain‐treated red blood cells, and that initially appeared to have anti‐S specificity. However, further studies revealed that the antibody, which did not have anti‐U specificity, recognized a determinant present on S+, s‐, U+, and S‐, s+,

Erythrocyte sialoglycoproteins and Plasmodium falciparum invasion
Transactions of the Royal Society of Tropical Medicine and Hygiene, 1983Human erythrocytes with a deficiency in glycophorin A (En(a-) cells) and glycophorin B (S-s-U- and S-s-U+ cells) show significant resistance in vitro to invasion by Plasmodium falciparum merozoites. Treatment of normal erythrocytes with trypsin and chymotrypsin also reduced invasion.

Isolation of murine sialoglycoprotein using consecutive chromatography
Life Sciences, 1991Affinity columns and high performance liquid chromatography were employed consecutively to obtain 89, 65, 46 and 29 kilodalton sialoglycoproteins from mouse erythrocyte ghosts free of the Band 3 protein which traditionally co-purifies with these proteins.
