WebFeb 17, 2015 · Simultaneous discriminative sensing of biothiols in vitro and in living cells has remained challenging. Herein, we report a new sulfonamide-based self-quenched fluorescent probe 1 for this purpose with high sensitivity and good selectivity. Treatment of 1 with cysteine (Cys), homocysteine (Hcy), or glutathione (GSH) yields aminoluciferin, 2 … WebTo further explore the probe's (TMN-NBD) performance in aqueous solution, the UV–vis absorption and fluorescence emission spectra of TMN-NBD in the presence of different biothiols (Cys, Hcy, GSH) were systematically studied in buffer solution (PBS/DMSO = 7:3, 20 mM, pH = 7.4) at 37 °C. As depicted in Fig. 1 a, d, and 1g, pure TMN-NBD showed a …
