Living cells dynamically change their morphology and function according to the cell cycle. Long-term observations of living cells are privileged when we spy the unique, cell cycle-driven molecular events, which cannot be obtained from short-term ones. Mg2+, a metal ion abundant in cells, has been shown to be involved in a variety of physiological phenomena by noninvasive cellular observation using fluorescence microscopy. However, long-term observation of Mg2+ in cells has been a great challenge. Herein, we present a protocol for the long-term microscopic imaging of intracellular Mg2+ levels using a small molecule-protein hybrid fluorescent probe we developed.
