DiBAC4(3) is a sensitive slow-response probe for measuring cellular membrane potential. In general, slow-response probes exhibit potential-dependent changes in their transmembrane distribution that are accompanied by a fluorescence change. The magnitude of response is much larger than fast-response probes. Slow-response probes, which include cationic carbocyanines, rhodamines and anionic oxonols, are suitable for detecting changes in average membrane potentials of nonexcitable cells caused by respiratory activity, ion-channel permeability, drug binding and other factors. DiBAC4(3) has been employed in flow cytometry to monitor antibacterial activity of defensins. Wavelength Maxima: Excitation 493nm, Emission 516nm Alternative name: bis-(1,3-Dibarbituric acid)-trimethine oxonol. Purity: ≥98% (HPLC). Solubility: Soluble in DMSO. Long Term Storage: -20°C.
