Effects of cholesterol on lipid organization in human erythrocyte membrane
The molar ratio of cholesterol to phospholipid (C/P) in human erythrocyte membrane is modified by incubating the cells with liposomes of various C/P ratios. The observed increase in cell surface area may be accounted for by the addition of cholesterol molecules. Fusion between liposomes and cells or attachment of liposomes to cells is not a significant factor in the alteration of C/P ratio. Ons...
متن کاملLocalization of Erythrocyte Membrane
The reactions of three organic mercurial compounds, chlormerodrin, parachloromercuribenzoate (PCMB), and parachloromercuribenzenesulfonate (PCMBS) with intact red blood cells, hemolyzed red cells, hemoglobin solutions, and hemoglobin-free ghosts have been characterized. Both PCMB and PCMBS react with only 2 to 3 sulfhydryl groups per mole of hemoglobin in solution, whereas chlormerodrin reacts ...

his study was conducted to investigate the values of the order parameter (S) and correlation time (τc) in electron spin resonance spectra for 5-DS(doxylstearic acid) and 16-DS (doxyl-stearic acid) in old normal controls and in patients with type 2 diabetes and stroke in order to assess any association between age-related disorders and membrane fluidity. Materials and Methods: We measured the me...
متن کاملPreparation of Erythrocyte Membrane
The effect of blood lead on erythrocyte membrane proteins was studied in 28 workers from a scrap lead refining factory and in 18 controls working in railway construction. Sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE) of the polypeptides in the erythrocyte membrane showed that bands 3 and 4-1 had significantly decreased while bands 2.3, 6, and 7 had significantly increase...
متن کاملMethylation of Erythrocyte Membrane
A cytosolic protein carboxyl methyltransferase (Sadenosyl-L-methi0nine:protein O-methyltransferase, E.C. 2.1.1.24) purified from human erythrocytes catalyzes the methylation of erythrocyte membrane proteins in vitro using S-adenosyl-~-[methyZ-~H]methionine as the methyl group donor. The principal methylaccepting proteins have been identified by sodium dodecyl sulfate-gel electrophoresis at pH 2...
