  • Title: Disproportional loss of membrane constituents in the course of erythrocyte aging.
    Author: Trautsch C, Tannert C, Maretzki D.
    Journal: Acta Biol Med Ger; 1981; 40(6):743-6. PubMed ID: 7324705.
    Abstract:
    Acetylcholine esterase activity and sialic acid content were estimated in human erythrocytes separated according to their densities and after fragmentation in vitro by heating or a combined hyperosmolaric-mechanical stress. In vivo aged cells showed a disproportional loss of both membrane constituents. Fragmentation of erythrocytes in vitro resulted in a proportional loss of acetylcholine esterase activity and sialic acid. Young cells are more prone to fragmentation by heat than older ones.
