Fig. 3. Time-dependent fluorescent response of probe 2 (1 μM) toward H2S (200 μM) and/or hNQO1 (1 μg mL–1). (A) 2 was treated with H2S and hNQO1 simultaneously, or only with hNQO1 (B) or H2S (C). (D) Time-dependent emissions at 535 nm for 2 treated with hNQO1 and H2S (black), hNQO1 (green), H2S (red) or probe 2 alone (blue) in PBS buffer.
