Sulfane Sulfur Probe 4

A fluorescent probe for sulfane sulfur species; subject to nucleophilic reaction in the presence of sulfane sulfur species resulting in the formation of fluorescein, which displays ex/em = 494/515 nm, respectively, and two molecules of 1,2-benzodithiol-3-one; has been used to determine localization of H2S3 in primary mouse neurons and to detect polysulfides in L. japonicus seedling roots
