不可渗透细胞的 pH 值指示剂（羧基 SNARF™-1 染料）的 pKa 为 ∼7.5，因此有助于测量 pH 值 7-8 之间的 pH 值变化。羧基-SNARF™-1 在酸性和碱性条件下分别显示出从黄橙色到深红色荧光的显著 pH 值依赖性发射波长变化。这种 pH 值依赖性使得可利用染料在两种发射波长（通常为 580 nm 和 640 nm）处的荧光强度比定量测定 pH 值。

Comparison of spectrum-shifting intracellular pH probes 5'(and 6')-carboxy-10-dimethylamino-3-hydroxyspiro[7H-benzo[c]xanthene-7, 1'(3'H)-isobenzofuran]-3'-one and 2',7'-biscarboxyethyl-5(and 6)-carboxyfluorescein.

'The dyes carboxy-SNARF-1 and BCECF are fluorescent probes of intracellular pH that exhibit changes in spectral shape upon proton binding which allow one to use measurements of fluorescence at two or more wavelengths in order to measure pH without artifacts associated with variability in dye loading, etc. In evaluating these

'Laser-induced fluorescence spectrometry is used to profile pH changes as droplets evaporate in an electrospray plume by measuring emission spectra of 2(or 4)-[10-(dimethylamino)-3-oxo-3H-benzo[c]xanthene-7-yl]-benzenedicarboxylic acid (carboxy SNARF-1), a pH-sensitive fluorescent dye. The observed pH changes depend on initial droplet pH and polarity. In some instances, small or negligible changes of pH
