Magnesium-sensitive microelectrodes were used to measure the intracellular concentration of free Mg2+, [Mg2+]f, in rat extensor digitorum longus muscles in vitro at 30 degrees C. The intracellular activities of Na+ and K+ were also determined so that allowance could be made for the interference from these ions with the Mg2+ electrode response. The mean value for [Mg2+]f based on twenty-six measurements in twelve muscles was 0.47 mM.
