AC-green (VDP-green) can respond to VDPs with more than 60-fold increase of emission in aqueous solution, while there is no significant interference from biological thiols, amino acids or inorganic salts.
AC-green (2 μM; 90 min) has no apparent fluorescence signal within the pH range of 5.0-9.0. Addition of rBSA turns on the fluorescence.
AC-gree (10 μM) has low cytotoxicity in HepG2 cells and Hela cells.
AC-gree (10 μM; for 15 min) images VDPs in living HepG2 cells and bright green fluorescence appeared. This fluorescence is inhibited when the cells are pretreated with PAO, a popular specificligand for protein vicinal dithiols.
AC-gree (10 μM; for 20 min) incubates with zebrafishes has a strong fluorescence signal appeared in the green channel.
