Fluo-3FF pentapotassium is a cell-permeable acetoxy-methyl ester of Fluo-3FF, a fluorescent calcium indicator. Fluo-3FF is a di-fluorinated analog of Fluo-3 with a 100-fold lower affinity than Fluo-3 for calcium Kds=42 and 0.4 ?M, respectively . For its low affinity, Fluo-3FF is used for studying compartments with high concentrations of calcium, such as endoplasmic reticulum, where high affinity dyes will be insensitive to luminal fluctuations.
