DiBAC4(3) is a negatively charged fluorescent membrane potential indicator.1 Upon membrane depolarization, DiBAC4(3) enters the cytosol, binds to lipid membranes and intracellular proteins, and displays excitation/emission maxima of 490/516 nm, respectively.1,2 It has been used to measure the membrane potential of live or fixed mammalian and bacterial cells by flow cytometry or fluorescence microscopy.2,3,4

Cell experiment: | Prior to the fluorescence measurements, cells are incubated in KRH (Krebs-Ringer-HEPES) buffer containing with 100 nM DiBAC4(3) for 20 min at room temperature. The stained cells are used for experiments without washing. The fluorescence emission is collected using a 505 nm dicroic mirror and a BA filter (>520 nm)[1]. |
