Description
Tetraphenylphosphonium (TPP+). A molecular probe in conjunction with an ion selective electrode (ISE) for measuring the mitochondrial membrane potential.

- For measurement of mitochondrial membrane potential, the inhibitory concentration of the probe molecule should be evaluated on the activity of respiration MiPNet14.05. This side effect of TPP+ and TPMP+ (and various dyes) is frequently ignored.
