-SulfoBiotics- HSip-1 - Amerigo Scientific

- Overview
  - It has been recognized that hydrogen sulfide (H2S) has an important role as a physiological active substance for vasodilation, cytoprotection, and modulation of insulin secretion. H2S is considered as a gaseous molecule such as nitric oxide and carbon monoxide. However, around 80% of the total sulfide exists as hydrogen sulfide anion (HS- ) under physiological condition, since the pKa is about 7. In addition, HS- easily converts to various biochemical molecules such as persulfides and polysulfides, which react with sulfhydryl moieties in a living body. -SulfoBiotics- HSip-1 is a novel fluorescent probe to detect H2S selectively and it emits strong green fluorescence when it reacts with H2S. -SulfoBiotics-HSip-1 DA is cell membrane permeable and it enables fluorescent imaging of intracellular H2S.
