Diffusible magnesium in frog skeletal muscle cells.

Abstract

Total diffusible magnesium concentration in frog skeletal muscle is 5.2 mM as determined by electron probe microanalysis of 0.2 nl liquid samples. The calculated free Mg concentration, 0.2 mM, is at the lower end of the range of values reported by others as calculated by methods using nuclear magnetic resonance, Mg-selective microelectrodes, and metallochromic indicator dyes. Magnesium is but one of many elements of physiological importance in muscle that can be analyzed using this novel liquid-sampling and x-ray spectroscopic method.
