Description:
PBFI AM is a cell-permeable, potassium-sensitive fluorophore used to measure potassium changes in cells and intracellular compartments. As PBFI AM enters cells, it is hydrolyzed by intracellular esterases to produce PBFI. The affinity of PBFI for potassium is sodium-dependent (Kd=44 and 5.1mM with or without sodium, respectively). Spectral data: lambdaEx=370nm; lambdaEm=540nm in methanol.
