Fig. 8. Representative recordings showing the change in transepithelial voltage
(Vt) following the addition of (A) 10 µmol
l–1 Tenmo-ADFb, (B) 1 nmol l–1 Achdo-KII and
(C) 1 mmol l–1 8-bromo cyclic GMP. Thick arrows show the time
of insertion (downward) and withdrawal (upward) of the microelectrode, and
thin arrows show when peptides were added. The horizontal bar in C shows when
8-bromo cyclic GMP was present in the perfusate, and the thin arrow indicates
the time of addition of 10 µmol l–1 Tenmo-ADFb.
