Figure 6: Response of SFP-2 using different thiol substrates.

From: Selective fluorescent probes for live-cell monitoring of sulphide

Figure 6

(a–c) Imaging of sulphide substrates in HeLa cells after 30 min incubation using SFP-2 (20). Images were obtained by using confocal fluorescence capture with 2 μM probe, with either: (a) 0 μM sulphide source, (b) 100 μM GSH, (c) 100 μM cysteine. Scale bar represents 40 μm.
