title: An unusual sialoglycoprotein associated with the Webb-positive phenotype.
abstract: 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. All Webb-positive individuals exhibited a decrease in the beta-sialoglycoprotein beta SGP band along with the appearance of a new SGP 3,000 daltons less than beta SGP. It is postulated that this band is an abnormal beta SGP possibly lacking the N-linked oligosaccharide that is normally present in beta-SGP.
