results from ( i ) the determination of the ligand conditions supporting binding , ( ii ) kinetics of association and dissociation from the na , k-atpase , ( iii ) affinity titration , ( iv ) selectivity , and ( v ) competition studies , when taken together , show that the endogenous digitalis-like factor is a specific inhibitor of the sodium pump that stabilizes the e2p form of the enzyme in a manner analogous to ouabain .
