Thermo Scientific Pierce 2-Mercaptoethanol (2-ME), also called beta-mercaptoethanol (b-ME), is a mild reducing agent for cleaving protein disulfide bonds.

Features of 2-mercaptoethanol:

• Also known as β-mercaptoethanol, beta-mercaptoethanol, bME, b-ME
• Mild but effective reducing agent, often included in enzyme solutions to protect against catalytic site inactivation due to cysteine sulfhydryl oxidation/disulfide formation; added at final concentrations of 5 and 20 mM, with or without EDTA, as an additional protectant
