Frequency-Dependent Capacitance of the Apical Membrane of Frog Skin: Dielectric Relaxation Processes

Impedance analysis of the isolated epithelium of frog skin (northern Rana pipiens) was carried out in the frequency range between 0.1 Hz and 5.5 kHz while Na + transport was abolished. Under these conditions, the impedance is determined almost completely by the dielectric properties of the apical me...
