Effect of ethylisopropylamiloride (EIPA) and DAPI on Na+-induced alkalinization of peptide nucleic acid-positive (PNA+) cells following Na+-free exposure at resting intracellular pH (pHi). A: representative trace demonstrating inhibition of cell alkalinization by EIPA (100 μM). B: quantitative analysis of cell alkalinization in the absence and presence of EIPA (∼62% inhibition). Values are means ± SE (n = 19 cells). *P < 0.001 (by paired t-test). C: representative trace demonstrating lack of effect on cell alkalinization in the presence of DAPI (1 μM). D: quantitative analysis of cell alkalinization in the absence and presence of DAPI. Values are means ± SE (n = 22). *P > 0.05 (by paired t-test).
