Membrane proteins in Rh+, Rh- and Rh: -29, 38 (- - -/- - -, rh) red cells compared by using SDS-polyacrylamide gel...

Since Rh: -29, 38 (- - -/- - -, rh) phenotype of the Rh blood groups (--- in text) revealed unusual red cells, such as stomatocytes and microspherocytes and the relatively shortened half life of 17 days, red cell membrane proteins from Rh + (D), Rh - (d) and --- were compared by using SDS-polyacrylamide gel electrophoresis (SDS-PAGE). No differences were observed among the patterns of the reduced and non-reduced membrane proteins from Rh+, Rh- and --- red cells. Two-dimensional gel electrophoresis of --- red cell membrane proteins also revealed a pattern similar to Rh+ and Rh- red cell membrane proteins. It is suggested that the lack of all Rh antigens causes no visible alteration of red cell membrane proteins detected by the method of Fairbanks G., Steck T.L. and Wallach D.F.H.
