Characterization of Endogenous and Extruded H 2 S and Small Oxoacids of Sulfur (SOS) in Cell Cultures

• Robert Brown

This report characterizes and quantifies endogenous hydrogen sulfide (H2S) and small oxoacids of sulfur (SOS = HOSH, HOSOH) in a panel of cell strains together with human most cancers (A375 melanoma cells, HeLa cervical cells) and noncancer (HEK293 embryonic kidney cells), in addition to E. coli DH5α and S. cerevisiae S288C. The methodology used is a translation of well-studied…
