Method "For measurements of total intracellular potassium levels, cells were washed with warm (37°C), slightly hypertonic glucose solution added drop-wise from a pipette." "Total and bound K+ were determined to allow the calculation of free K+ within the cell, which is the fraction that balances the charge of osmotically active anions."
Comments "[Researchers] saw no significant difference in the concentration of free or bound K+ in cells treated with weak acids compared to untreated control cells (Table 2). The distributions of the K+ pool between the fixed and mobile anion pools in the presence and absence of acetate were similar (Table 2)." See note beneath table.
