Rubidium bromide functions as a source of rubidium ions in various experimental applications. It interacts at the molecular level by dissociating into rubidium and bromide ions when dissolved in water or other solvents. At the cellular level, rubidium bromide may influence ion channels and membrane potential, affecting cellular signaling and function. Its mechanism of action involves its ability to modulate certain biological processes and pathways, which can be useful in understanding cellular function and in experimental studies of ion transport and signaling.
