Sialoglycoprotein and carbohydrate complexes in chromium toxicity
Current Opinion in Chemical Biology, 2003Chromium(VI) compounds are amongst the most widely encountered industrial carcinogens and are of increasing concern with respect to environmental exposure. Sialoglycoproteins and carbohydrates play a crucial role in stabilizing oxoCr(V) intermediates, which are produced by extracellular and intracellular reduction of chromium(VI).

The major sialoglycoprotein of human T-lympocytes
Carbohydrate Research, 1980Human, peripheral-blood T-lymphocytes and human, T-lymphoblastoid cells of a MOLT 4B cell-line were surface-labeled by lactoperoxidase-catalyzed iodination, periodate and sodium borotritide, and galactose oxidase and sodium borotritide, and analyzed by dodecyl sodium sulfate-polyacrylamide gel-electrophoresis.

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.

Another MNSs variant producing a hybrid MNSs sialoglycoprotein
Revue Francaise de Transfusion et Immuno-hématologie, 1982Summary The red cells of a propositus, A.G., and those of her compatible sister, A.C., were M+N−S+s− but, after trypsin treatment, they failed to react with Vicia graminea lectin. The phenotype of A.G. closely resembled that of J.R. [17], except that the cells of both A.G. and A.C. were agglutinated very weakly by an anti-Hil serum. All three were Wr(

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.

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.

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 ...

An Unusual Sialoglycoprotein Associated with the Webb-Positive Phenotype
Vox Sanguinis, 1986Abstract. This paper presents the results of a study on the erythrocyte membrane proteins from Webb‐positive individuals. The membrane proteins were separated by polyacrylamide electrophoresis and stained using a Silver stain as well as Coomassie blue and PAS stains.

A minor sialoglycoprotein of the human erythrocyte membrane
Archives of Biochemistry and Biophysics, 1980Abstract The sialoglycoprotein periodate fuchsin sulfite 2 has about 8% of the sialic acid contained in the sialoglycoproteins of the human erythrocyte membrane. This polypeptide appears to have an apparent monomeric molecular weight of 35,000, somewhat smaller than the monomer of the major sialoglycoprotein (periodate fuchsin sulfite 1) as judged by

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%.
