Sodium mercaptoacetate (sodium thioglycolate) ≥97% for bacteriology

Supplier: MP Biomedicals
Description: Thioglycolic acid protects tryptophan in amino acid analysis,and also mediates formation of ATP from ADP. It lowers the oxidation-reduction potential and neutralises mercurial preservatives. An inhibitor of fatty acid oxidation. An agent that prevents the metabolism of fatty acids and stimulates feeding. The sodium salt form is typically used in production of bacteriological culture media. The free acid is used as a reagent for the sensitive detection of iron (a blue color appears in the presence of ferric iron, and when an alkali hydroxide is added to a solution containing ferrous salts and thioglycolic acid, a yellow precipitate forms), molybdenum, silver and tin; used for the extraction and spectrophotometric determination of various transition metals such as lead, tungsten, molybdenum and titanium.
