Description
An uncoupler is a protonophore (CCCP, FCCP, DNP, SF6847) which cycles across the inner mt-membrane with transport of protons and dissipation of the electrochemical proton gradient. Mild uncoupling may be induced at low uncoupler concentrations, the noncoupled state of ET capacity is obtained at optimum uncoupler concentration for maximum flux, whereas at higher concentrations an uncoupler-induced inhibition is observed. We therefore recommend multiple uncoupler titrations until the maximum respiratory flux, ET capacity, is achieved.
