Abstract

We report two-photon probes (FMg1 and FMg2) that can selectively detect intracellular free Mg²⁺ ([Mg²⁺]_i) in live cells and tissues by two-photon microscopy. Combined with BCaM, a two-photon probe for near-membrane Ca²⁺ ([Ca²⁺]_m), FMg2 allows dual-color imaging of Mg²⁺/Ca²⁺ activities in live cells and [Mg²⁺]_i /[Ca²⁺]_m distributions in live tissues at a depth of 100-200 μm.
