Description: H2S fluorescent probe
Chemical Name: N-[2-[(Acetyloxy)methoxy]-2-oxoethyl]-N-[(3',6'-diazido-3-oxospiro[isobenzofuran-1(3H),9'-[9H]xanthen]-5-yl)carbonyl]glycine (acetyloxy)methyl ester
Biological Activity for Sulfidefluor 7 AM
Sulfidefluor 7 AM is a reported to be a hydrogen sulphide (H2S) fluorescent probe. Contains an acetoxymethyl ester, which enhances cell permeability and is hydrolyzed inside the cell to trap the probe. Used to visualize VEGF-induced H2S production in human umbilical vein endothelial cells (HUVECS). Excitation wavelength ~ 495 nm; emission maximum ~ 520 nm.
