Invitrogen™ PBFI, AM, cell permeant - Special Packaging

PBFI is a potassium-sensitive molecule used measure intracellular K⁺ fluxes in animal cells and in plant cells and vacuoles. Although the selectivity of PBFI for K⁺ is less than that of calcium indicators such as fura-2, it is sufficient for the detection of physiological concentrations of K⁺ in the presence of other monovalent cations. The spectral response of PBFI upon ion binding permit excitation ratio measurements, and this indicator can be used with the same optical filters and equipment used for fura-2
