The effects of macrocyclic compounds on cation transport in sheep red cells and thin and thick lipid membranes.
TL;DR: It was found that the thin lipid membranes have ionic permeability properties which are vastly different from those of intact HK and LK sheep red cell membranes, and the Na + and K + transport properties of the two genetic types of sheep red cells are significantly different.
The Effect of Valinomycin on Potassium and Sodium Permeability of HK and LK Sheep Red Cells
TL;DR: A cyclic depsipeptide antibiotic, valinomycin, was found to produce increased selective permeability of the plasma membranes of HK and LK sheep red blood cells to potassium but not to sodium ions, and it is proposed that the selective cation permeability produced by this compound depends primarily on steric factors.
Stimulation of active potassium transport in LK sheep red cells by blood group-L-antiserum.

TL;DR: It is indicated that the formation of a complex between the L-antigen and its antibody stimulates active transport in LK sheep red cells both by changing the kinetics of the pump and by increasing the number of pump sites.

Separation of adenosine triphosphatase of HK and LK sheep red cell membranes by density gradient centrifugation.
D. C. Tosteson,P. Cook,R. Blount +2 more
TL;DR: The possibility that sensitivity of sheep red cell membrane ATPase to Na + K depends on the association between units containing the enzyme(s) and large, light, phospholipid-containing components is discussed.

Effect of membrane potential and internal pH on active sodium-potassium transport and on ATP content in high-potassium sheep erythrocytes.
TL;DR: It was found that an increased cellular pH reduced the rates of active transport of Na+ and K+ without significantly altering the ratio of pumped Na+/K+.
