33215623-0	2021	Lysosome-targeting pH indicator based on peri-fused naphthalene monoimide with superior stability for long term live cell imaging.	naphthalene monoimide	52-73	phenylalanine hydroxylase	Homo sapiens	19-21
33215623-5	2021	Here, we describe the synthesis and spectroscopic properties of a novel small molecule marker for lysosomes based on naphthalene monoimide with reversible, pH-dependent spectral shifts in both the absorption and the emission spectrum and acidity-associated changes in fluorescence lifetime.	naphthalene monoimide	117-138	phenylalanine hydroxylase	Homo sapiens	156-158
