图1：Fluorescence ofcoumarin1 (C1) at p-nitrophenol (pNP) concentrations from 0.4× 10 −6 to 0.173 × 10 −3 M. (i) C1, (ii) C1 +WT, (iii) 0.4M, (iv) 0.7 M,
(v) 1.8 M, (vi) 3.5 M, (vii) 7 M, (viii) 18 M, (ix) 35 M, (x) 87 M, and (xi) 173 M. (b) Calibration curve with p-nitrophenol. Relative fluorescence intensity change (RFI) is plotted as a function of added p-nitrophenol (pNP) concentration. (c) Fluorescence of Coumarin1 at p-nitrophenol (pNP) concentrations from 0.4× 10 −6 to 0.173 × 10 −3 M in absence of OPH; (i) C1, (ii) 0.4M, (iii) 0.7 M, (iv) 1.8 M, (v) 3.5 M, (vi) 7 M, (vii) 18 M, (viii) 35 M, (ix) 87 M, and (x) 173 M. All the experiments were conducted in the absence/presence of OPH in 20mM CHES buffer, pH 9.0. [Coumarin1] =2.33 × 10 −8 M. Coumarin1 was excited at 343 nm. Coumarin1: OPH= 1:1.
