Description

Application

2-Mercaptoethanesulfonic acid salts (Coenzyme M potassium salt, MESK) are used as an antioxidant and cytoprotective agent in a wide variety of applications from protection from toxicity of therapeutic agents, such as cyclophosphamide and to prevention of brain injury damage.

Biochem/physiol Actions

Metabolite in microbial metabolism in diverse environments and methane metabolism ; methanogens use 2-mercaptoethanesulfonate (CoM; coenzyme M) as the terminal methyl carrier in methano-genesis; can be determined with chemiluminescence detection by flow injection analysis.

Packaging

Bottomless glass bottle. Contents are inside inserted fused cone.
