In Vitro	The membrane hyperpolarization induced by 10 μM Evans blue (EB) in HEKBKα is clearly observed with DiBAC4(3), while the change in membrane potential (MP) by addition of 3 mM tetraethylammonium chloride (TEA) appears more slowly than that measured with microelectrode. The time to peak of hyperpolarization is 2.3±0.9 s (n=4) and 35.0±2.6 s (n=12, P<0.01) by the measurements with microelectrodes and DiBAC4(3), respectively[1].
Cell Assay	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].
