Sodium-binding benzofuran isophthalate (SBFI) is a cell-impermeant fluorescent dye primarily used for the detection of sodium ions (Na+). Excitable at 340 nm, SBFI emits fluorescence at 450 nm, allowing for sensitive detection of sodium concentrations in biological samples. This compound exhibits selectivity for Na+ over potassium ions (K+), with dissociation constants (Kd) of 20 mM and 120 mM, respectively. SBFI is valuable for research applications involving ion transport and signaling in cellular environments.
