Erythrocyte Membrane Elasticity and Viscosity
Annual Review of Physiology, 1987The classical theory of elasticity (35) treats the material of a deformable body as a three-dimensional continuum in which internal stresses occur as the body is deformed by external forces acting over its surface. Although the internal stresses are caused by the displacement of atoms or molecules from an original state of equilibrium, the molecular ...

Surface proteins of erythrocyte membranes
Biochimica et Biophysica Acta (BBA) - Biomembranes, 1971Abstract Diazotized sulfanilic acid labeling and trypsin digestion studies of human and bovine erythrocytes indicate that the glycoprotein of each species is the only major membrane protein which is readily accessible at the cell surface. Trypsin digestion of isolated human erythrocyte membranes under conditions identical to the erythrocyte digestion

Interaction of ticlopidine with the erythrocyte membrane
Biochemical Pharmacology, 1982The membrane effects of ticlopidine on the erythrocyte membrane were explored by the spin label method at the proteic and phospholipidic levels. This spectroscopic study was completed by polyacrylamide gel electrophoresis of proteins, measurement of the protection against haemolysis and observation of the erythrocyte shape changes induced by the drug ...

The phosphoproteins of the sickle erythrocyte membrane
Archives of Biochemistry and Biophysics, 1986The uptake of 32P from exogenous 32Pi into membrane proteins of sickle erythrocytes has been analyzed. The phosphorylation of spectrin is normal in sickle cells. There is, however, a substantial increase in 32P in the sialoproteins of the membrane, which can be demonstrated after fractionation or selective proteolysis.

Adsorptive immobilization of erythrocyte membrane
Journal of Biotechnology, 2000Immobilization of human erythrocyte membrane was carried out by adsorption on Fractosil, a porous form of silica. Acetylcholinesterase (AChE) was chosen as a representative membrane enzyme in this study. Dependency of adsorption on membrane concentration was determined.

Physicochemical Investigations of Erythrocyte Membranes
Nature, 1958A SMALL drop of citrated human blood is placed on a slide next to a somewhat larger drop of Ponceau 2R and the two drops are mixed, covered with a cover glass and examined both with ordinary and polarized light. Under the double action of the dye and the hypotonicity, all the red cells become perfectly spherical with a diameter ranging from 5.0 to 5.6µ

Calcium binding to the erythrocyte membrane
Acta Histochemica, 1976Calcium binding sites of human red blood cells were localized by means of a method according to OSCHMAN and WALL (1972). The procedure resulted in multiple opaque deposits at the inner surface of the erythrocyte membrane.

The Erythrocyte Membrane Skeleton: Biochemistry
Hospital Practice, 1984The erythrocyte is exposed to turbulence and powerful shearing forces as it moves through the arterioles at high speeds and pressures. In addition, it must bend almost double to pass through the spleen every 12 minutes. To survive those repeated stresses, the red cell must be both flexible and durable—properties now known to depend on its membrane ...

Proteins of the camel erythrocyte membrane
Biochimica et Biophysica Acta (BBA) - Biomembranes, 1975Electrophoresis on polyacrylamide gels containing dodecyl sulphate has revealed that the major proteins of the camel erythrocyte membrane are similar to those of the human and bovine species in both electrophoretic mobility and relative abundance. The major difference lies in the major intrinsic membrane protein of molecular weight approx. 100 000.

Calcium binding by the erythrocyte membrane
Biochimica et Biophysica Acta (BBA) - Biomembranes, 1973Abstract Calcium binding to isolated erythrocyte membranes was stimulated by ATP. This stimulatory effect of ATP required Mg 2+ . Ethacrynic acid and ruthenium red inhibited the stimulatory effect of ATP. About 80% of the bound Ca 2+ was associated with the membrane protein.
