Proteins of the turkey erythrocyte membrane
Biochemistry, 1976A 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 ...

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.

Carcinoembryonic Antigens of Erythrocyte Membranes
Nature New Biology, 1973The 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 ...

The Erythrocyte Membrane Skeleton: Pathophysiology
Hospital Practice, 1984Given the evident importance of the membrane skeleton in preserving shape and structural integrity of the erythrocyte, one would expect that disorders involving abnormalities of shape or fragility ...

Erythrocyte Membrane: Chemical Modification
Science, 1965Erythrocytes treated with 1-fluoro-2,4-dinitrobenzene become permeable to Na + and K + , but not to small water-soluble nonelectrolytes or hemoglobin, and eventually lyse in isotonic buffer. Erythrocytes treated with 1,5-difluoro-2,4-dinitrobenzene become permeable to Na +

Erythrocyte membrane transport.
Novartis Foundation symposium, 1999Erythrocytes are endowed with functional entities that support either cellular functions or the systemic delivery of O2 from lung to tissue and removal of CO2 from tissue to lung. The latter depend largely on the blood's circulatory capacity. They are associated, respectively, with cytosolic haemoglobin and the major membrane polypeptide band 3 (anion ...

Proteins and glycoproteins of the erythrocyte membrane
Archives of Biochemistry and Biophysics, 1972Abstract 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 ...

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 ...

Erythrocyte membrane transport physiology
Current Opinion in Hematology, 1997Several transport pathways are involved in the regulation of cell volume and ion content in the human erythrocyte. Studies of these pathways have shown that K-Cl contransport and the Ca-gated K channel (Gardos channel) play an important role in the dehydration of sickle erythrocytes.
