Abstract
Reactive sulfur species have been recognized as an important regulator in redox biology, wherein the reactive sulfur species have been shown to be active in tumor suppressors, ion channels, and transcription factors. The disclosed invention is a novel composition of matter that allows for the detection of H2S and H2Sn species in living cells. These novel compositions represent significant progress in the field of chemical, H2S and H2Sn probes as they have both been successfully applied in the visualization sulfur species in living systems.
