On demandInvitrogen™ SBFI, AM, cell permeant
SBFI is a sodium-sensitive molecule used to estimate Na+ gradients in isolated mitochondria, to measure intracellular NA+ levels, to measure Na+ efflux in cells, and, in combination with other fluorescent indicators used to correlate changes in intracellular Na+ with Ca2+ and Mg2+ concentrations, intracellular pH, and membrane potential. Although the selectivity of SBFI for Na+ is less than that of calcium indicators such as fura-2, it is sufficient for the detection of physiological concentrations of Na+ in the presence of other monovalent cations. The spectral response of SBFI upon ion binding permit excitation ratio measurements, and this indicator can be used with the same optical filters and equipment used for fura-2
