A ratiometric fluorescent probe for monitoring pH fluctuations during autophagy in living cells

We present a ratiometric fluorescent probe for monitoring pH featuring superb photostability and chemostability. The down-regulation of the intracellular pH during autophagy in living cells induced by various stimuli, including several drugs and starvation, was quantified, which could provide instructive value to construct autophagy models to study the related pathological processes.

Automated summary

The ratiometric fluorescent probe presented in this study offers excellent photostability and chemostability for monitoring pH changes in living cells. Quantifying the down-regulation of intracellular pH during autophagy induced by various stimuli can provide valuable guidance for constructing autophagy models to study related pathological processes.
