"WebbNigericin has been employed to study anion transport ( Section 2.5) and to modify the pH gradient across energy-conserving membranes. It is often stated that nigericin abolishes ΔpH across a membrane; in fact, the ionophore equalises the K + and H + concentration gradients, with the final ion gradients depending on the experimental conditions.
