Abstract
Tl+ stoichiometrically displaced K+ in frog muscle cells. This displacement was independent of the function of cell membrane and postulated pumps and of a macroscopic electric charge or Donnan effect. Cs+ and Tl+ competed for the adsorption sites normally occupied by K+. Cs+ and Tl+ competed for the adsorption sites normally occupied by K+. Cs+ and Tl+, like K+, were primarily localized in the A-band of the muscle myofibrils.
