Conference paper


The Na,K-ion pump is responsible for the transport of sodium and potassium across the cell membrane, where it catalyzes primary active transtubular transport of sodium and secondary active transport of other solutes. The concentration of the Na,K-pump is particularly high in the thick ascending limb of Henle. It can be purified from the outer renal medulla as an enzyme, Na,K-ATPase, by selective extraction of extraneous proteins from the plasma membranes without destroying native lipoprotein associations (Jørgensen 1980).
