Fusion of Human Red Blood Cell Membranes
The ability of the parainfluenza group of viruses to induce cell fusion with the production of polykaryocytes and heterokaryons of animal cells has been well documented (1, 2, 3, 4) . Much of the interest in cell fusion in recent years has centered on cell hybrids with nuclei of different species occupying the same cell . Such hybrid cells have proved useful for studies of nuclear-cytoplasmic r...
متن کاملPolypeptide chains from human red blood cell membranes.
Human red blood cell membranes contain at least 17 polypeptides of differing molecular weight ranging from 27,000 to 220,000. Previous publications have reported higher values for the largest molecular weight species, but are in error owing to incorrect calibration of sodium dodecylsulfate-polyacrylamide gels with unreduced proteins. The two highest molecular weight species which constitute app...
متن کاملMeasurement of the nonlinear elasticity of red blood cell membranes.
The membranes of human red blood cells (RBCs) are a composite of a fluid lipid bilayer and a triangular network of semiflexible filaments (spectrin). We perform cellular microrheology using the dynamic membrane fluctuations of the RBCs to extract the elastic moduli of this composite membrane. By applying known osmotic stresses, we measure the changes in the elastic constants under imposed strai...
متن کاملKinetics of chloride transport across fish red blood cell membranes
The continuous flow tube method was used to investigate the kinetics of chloride transport, and its potential oxygenation-dependency, in red blood cells (RBCs) from four teleost fish species and man. A significant interspecific variation in Cl- transport kinetics was found. At 15 °C, the rate constant k for unidirectional 36Cl- efflux was significantly lower in RBCs from eel and carp than i...
متن کاملMicrorheology of red blood cell membranes using dynamic scattering microscopy.
We employ a novel optical technique, dynamic scattering microscopy (DSM), to extract the frequency dependence of the viscoelastic modulus associated with the red blood cell membrane. This approach applies the principle of dynamic light scattering to micro beads attached to the red blood cell membrane in thermal fluctuation. This allows for highthroughput characterization of a large number of ce...
