About AcidiFluor ORANGE

AcidiFluor™ ORANGE is a fluorescence imaging probe which enhances fluorescence dramatically in acidic environments. This probe can stain acidic organelles such as lysosomes, late endosomes and granules selectively. It’s excellent selectivity enables detection of acidic environments. At pH 5.0, identical to the environment of acidic organelles, the fluorescence intensity is 50-fold or more compared to the intensity at pH 7.4.
