Description: Sulfidefluor-7 AM (SF7-AM) is an effective and cell permeable fluorescent probe for hydrogen sulfide (h2s). Sulfidefluor-7 AM contains acetoxy-methyl ester, which is hydrolyzed intracellular to capture the probe. Smiles:...

SF7-AM is a cell-trappable fluorogenic probe for the detection of hydrogen sulfide (H2S). Following entry into cells, cleavage of the acetoxymethyl ester groups by intracellular esterases results in an anionic charge, trapping the probe inside the cells. Reaction of the azide moieties with H2S in buffers or live...
