Gibco™ 2-Mercaptoethanol (also known as beta-mercaptoethanol or BME) is a potent reducing agent used in cell culture media to prevent toxic levels of oxygen radicals. 2-Mercaptoethanol is not stable in solution, so most protocols require daily supplementation. Gibco 2-Mercaptoethanol contains 2-mercaptoethanol at a concentration of 55 mM in Dulbecco's phosphate buffered saline (DPBS).
