Characterization of anion transport system in trout red blood cell

Abstract: Anion transport in the trout red blood cell is mediated by a membrane protein that selectively binds dihydro-4,4'-dithiocyanostilbene-2,2'-disulfonic acid (3H2DIDS) and that forms on sodium dodecyl sulfate (SDS)-polyacrylamide gel electropherograms a band with the same diffuse structure at the same location as the band 3 protein of the mammalian red blood cells. There exists a linear relationship between binding of H2DIDS to this protein and the inhibition of anion equilibrium exchange. At maximal inhibition a… Show more

“…In lanes d and e are shown the electrophoresis patterns of membranes incubated on ice and at 15°C, respectively, for 3 h without any enzyme. The large 100-kDa band visible is the anion exchanger band 3, the major integral protein of red blood cell [19,22]. One can see that incubation at 15°C did not produce any protein degradation.…”

“…in solution A containing 5 mM glucose and stored overnight at 4°C. Membrane preparation was obtained according to [19]. The suspension was centrifuged and the erythrocytes were hypotonically lysed at 0°C by diluting 1 ml of compacted cells into 10 ml of solution B containing 15% sucrose and 1% saponin, solution B consisting of 50 mM NaCl, 4 mM KCl, 5 mM CaCl 2 , 1 mM MgCl 2 , 15 mM Hepes, pH 7.5, and 10 µl/ ml Pefabloc (Boehringer) to inhibit proteases.…”

“…Транспорт сульфату в еритроцити у сульфатному середовищі пов'язаний з пере-міщенням Н + [9]. Можна припустити, що у разі пошкодження мембран аніони SO 4 2-і, відповідно, іони водню проникатимуть в еритроцити додатковим неспецифічним шляхом.…”

“…Транспорт іонів водню в еритроцитах у сульфатному середовищі без буфера до-сліджували в термостатованій (37 °С) посу-дині з рН-електродом, постійно перемішуючи клітинну суспензію [9]. При внесенні еритро-цитів до ізотонічного розчину Na 2 SO 4 , що не містить буферних компонентів, відбувається двофазна зміна рН зовнішнього середовища -закиснення з подальшим залуженням.…”
