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 ...

Sphingomyelinase of chicken erythrocyte membranes
Archives of Biochemistry and Biophysics, 1975Abstract Most of the chicken erythrocyte's sphingomyelin is hydrolyzed when the chicken red blood cells are incubated in hypotonie solution at 37 °C. Addition of detergents, such as Triton X-100 or Na-cholate, is essential for hydrolysis of external [3H ]sphingomyelin by the erythrocyte membranes.

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 +

Membrane Abnormalities in Polyagglutinable Erythrocytes
Acta Haematologica, 2009Polyagglutinable erythrocytes cause difficulty and delay in blood grouping and crossmatching. Abnormality of the erythrocyte membrane is the fundamental cause of some types of polyagglutinability. The altered chemical structure of the red cell membrane in various forms of polyagglutination isdescribed, with particular reference to the application of ...

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.

1995
The majority of the blood group characters treated in this monograph are defined as serological properties of the erythrocyte membrane. The expression of these characters is highly influenced by the structure and prevailing constitution of the membrane. It is therefore appropriate to present a concise survey on membrane composition and structure.

Studies on the succinylation of erythrocyte membranes
Biochimica et Biophysica Acta (BBA) - Biomembranes, 1972Abstract A method is described for the solubilization of the erythrocyte membrane by means of succinylation. In this procedure lipids and proteins are solubilized into an aqueous phase. The physical properties of this preparation were studied by optical rotatory dispersion, circular dichroism and infrared spectroscopy.

Erythrocyte deformability in diabetes and erythrocyte membrane lipid composition
Metabolism, 1990Erythrocyte deformability was assessed in 40 diabetic patients, 24 insulin-dependent (IDD) and 16 non-insulin-dependent (NIDD), by measuring the initial filtration flow rate of whole blood, isolated red blood cells (RBC), and isolated RBC membranes with the Hanss hemorheometer, and its relationship to the plasma and ghost membrane lipid composition was

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.
