Mag-indo-1 AM is a membrane-permeant fluorescent indicator for intracellular magnesium. It can be loaded into cells via incubation, and hydrolyzed to mag-indo-1 by cytosilic esterases.

Mag-indo-1/AM is a cell-permeable fluorescent indicator for Mg2+ and also for Ca2+ (Ex=340-390 nm, Em=410-490 nm). Mag-indo-1/AM can be used to determine intracellular Mg2+ and Ca2+ concentrations[1][2].
