the association and dissociation rate constants for the interaction of [ 3h ] -ouabain with partially purified rat brain ( na+ , k+ ) -atpase ( atp phosphohydrolase , ec 3.6.1.3 ) in vitro were estimated from the time course of the [ 3h ] -ouabain binding observed in the presence of na+ , mg2+ and atp by a polynomial approximation-curve-fitting technique .
