Tetramethylrhodamine ethyl ester perchlorate

Catelog Number: A16-0054

Category: Cell and Orgenella Stains

Description

Tetramethylrhodamine ethyl ester (TMRE) perchlorate is a cell-permeant red fluorescent probe commonly used to monitor membrane potential of mitochondria using live cell fluorescence microscopy and flow cytometry. TMRE is a lipophilic cation accumulated by mitochondria and exhibits a red shift in the emission of 575 nm. However, when the membrane is depolarized, as in apoptosis, TMRE is not accumulated in the mitochondria. Thus, the strength of the fluorescence signal in mitochondria is used to assess cell viability.
