| Method |
Concentration of 1nM in a cell volume of 1 um^3 corresponds to one molecule/cell (BNID 102 068), concentration of K+ ions of 180-200 mM (BNID 104049) corresponds to 1.8X10^8-2X10^8 molecules/cell. Measurement method of primary source: non-invasive microelectrode ion flux (MIFE) measurement technique. |
| Comments |
Under range of 0.3-3.5 Os×Kg^-1 External osmolality of sucrose in medium. See figure 3. K+ is the most abundant inorganic ion in the (non-halophilic) cell cytosol (a typical concentration of ~200 mM) |
