Low potassium-type (LK) sheep red blood cells show a significant increase of the residual (i.e., ouabain-insensitive) K+ influx when the ionic strength of the solution is decreased. This effect is absent from high potassium-type (HK) sheep red blood cells. The KCl cotransport system is not involved since three different manoeuvres to suppress the KCl cotransport (replacement of Cl- by NO3-, volume-decrease, inhibition by anti-L1 antibodies) have no effect on the low ionic strength-stimulated K+ influx.

UI	MeSH Term	Description	Entries
D009994	Osmolar Concentration	The concentration of osmotically active particles in solution expressed in terms of osmoles of solute per liter of solution.

D010042	Ouabain	A cardioactive glycoside consisting of rhamnose and ouabagenin, obtained from the seeds of Strophanthus gratus and other plants of the Apocynaceae; used like DIGITALIS. It is commonly used in cell biological studies as an inhibitor of the NA(+)-K(+)-EXCHANGING ATPASE.	Acocantherin,G-Strophanthin,Acolongifloroside K,G Strophanthin
D011188	Potassium	An element in the alkali group of metals with an atomic symbol K, atomic number 19, and atomic weight 39.10. It is the chief cation in the intracellular fluid of muscle and other cells. Potassium ion is a strong electrolyte that plays a significant role in the regulation of fluid volume and maintenance of the WATER-ELECTROLYTE BALANCE.
