Fig. 7. Profiles of the basolateral membrane voltage deflections
(
Vbl) along the length of Malpighian tubules of
Aedes aegypti. Cell 1 was voltage-clamped at a hyperpolarizing
voltage of 40 mV, and the voltage deflections across the basolateral membranes
of cells 2 and 3 recorded in the absence (control) and presence of
leucokinin-VIII. Values are mean ± s.e.m. of 14 experiments.
