Erythrocyte membranes: Effects of sonication

Biochimica et Biophysica Acta (BBA) - Biomembranes, 1968
Abstract Chromatographic, ultracentrifugal and electron-microscopic studies show that sonication of red blood cell membranes breaks these membranes into small vesicles and linear fragments having intact unit membrane structures. These fragments are from 100 to 600 A in size and do not sediment under conditions usually used to define solubility.

The Erythrocyte Membrane Skeleton: Biochemistry

Hospital Practice, 1984
The 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 ...

Carcinoembryonic Antigens of Erythrocyte Membranes

Nature New Biology, 1973
The carcinoembryonic antigen (CEA) of Gold and Freed-man1 was first described as being specific for tumours and foetal tissue of endodermal origin. This glycoprotein, or some antigenically related counterpart, has been shown by radioimmunoassay and other procedures to occur in the urine, plasma and faeces of healthy subjects and in patients bearing a ...

Adsorptive immobilization of erythrocyte membrane

Journal of Biotechnology, 2000
Immobilization 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.

Calcium binding by the erythrocyte membrane

Biochimica et Biophysica Acta (BBA) - Biomembranes, 1973
Abstract 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.

Proteins and glycoproteins of the erythrocyte membrane

Archives of Biochemistry and Biophysics, 1972
Abstract Erythrocyte membranes from several species were prepared by three different methods of hypotonic hemolysis and examined for variations in protein and glycoprotein content by acrylamide gel electrophoresis in sodium dodecyl sulfate. Significant variations were noted in morphology of the membranes prepared by the different methods without ...

Proteins of the camel erythrocyte membrane

Biochimica et Biophysica Acta (BBA) - Biomembranes, 1975
Electrophoresis 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.

Proteins of the turkey erythrocyte membrane

Biochemistry, 1976
A new and simplified method is described for preparation of turkey erythrocyte membranes which are essentially devoid of supernatant or nuclear contamination, but retain catecholamine-sensitive adenylate cyclase activity. These membranes have been solubilized in sodium dodecyl sulfate and analyzed by polyacrylamide gel electrophoresis and the major ...

Surface proteins of erythrocyte membranes

Biochimica et Biophysica Acta (BBA) - Biomembranes, 1971
Abstract 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, 1982
The 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 ...
