**JC-D7**/ JC-D8 demonstrate high selectivity for the labeling of polyP that was not sensitive to a number of ubiquitous organic polyphosphates, notably RNA. Use of these probes allowed us to demonstrate the real time detection of polyP release from lysosomes in live cells.

Overexpression of mitochondrially targeted, GFP-labeled polyphosphate kinase (mgPPK) results in increased level of** JC-D7** fluorescence. (A, inset) Colocalization profile estimated from fluorescence intensity measured along the arrow, shows that areas with increased levels of mtPPK expression correspond to areas with increased levels of endogenous polyphosphate.
