Kinetics 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 کاملFusion 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 کاملKinetics of bicarbonate transport in human red blood cell membranes at body temperature
We studied unidirectional [14C]HCO3- efflux from human resealed red cell ghosts with 1 mM acetazolamide under self-exchange conditions at pH = pH(i = o) 7.4-9.0 and 0-38 degrees C by means of the Millipore-Swinnex and continuous flow tube filtering techniques. 14CO2 loss from cells to efflux medium and further to the atmosphere was insignificant. [14C]HCO3- efflux was determined at pH 7.8, 38 d...
متن کاملThe asymmetry of chloride transport at 38 degrees C in human red blood cell membranes
Band 3-mediated Cl- exchange in human red blood cells and resealed ghosts was measured at 38 degrees C by the continuous flow tube method. When external Cl- concentration, C(o), is varied with constant internal Cl- concentration, C(i), the flux fits a simple Michaelis-Menten saturation curve (MM fit), with K1/2o = 3.8 +/- 0.4 mM. When the Cl- concentration is varied simultaneously at both sides...
متن کاملAnion transport inhibitor binding to band 3 in red blood cell membranes
The inhibitor of anion exchange 4,4'-dibenzoamido-2,2'-disulfonic stilbene (DBDS) binds to band 3, the anion transport protein in human red cell ghost membranes, and undergoes a large increase in fluorescence intensity when bound to band 3. Equilibrium binding studies performed in the absence of transportable anions show that DBDS binds to both a class of high-affinity (65 nM) and low-affinity ...
