Acrylamide is a monomer used in a variety of synthetic processes to form polymers and copolymers. It polymerizes in the presence of free radicals in aqueous solutions. It is usually used to prepare polyacrylamide gels for electrophoresis separation of biomolecules. Common reaction initiators are riboflavin and ammonium persulfate; varying the ratio of acrylamide to crosslinking agent permits the formation of a gel with predictable average pore size and texture. Acrylamide tends to hydrolyze under acidic or basic conditions to form acrylic acid. Polyacrylamide plastics have numerous commercial applications, due in part to the tendency of polyacrylamide to adsorb many times its own mass in water. Acrylic acid and any ionic impurities in the acrylamide can have significant effects on the performance of the acrylamide gel formed, since the voltage across the gel is affected by the ionic charge of the gel and usage buffers.

2-Mercaptoethanol is a hybrid of ethylene glycol and 1,2-ethanedithiol. It is used to reduce disulfide bonds and can act as a biological antioxidant by scavenging hydroxyl radicals. It is widely used because the hydroxyl group confers solubility in water and lowers the volatility. Due to its diminished vapor pressure, its odour, while unpleasant, is less objectionable than related thiols.
2-Mercaptoethanol is used to reduce disulfide linkages in solubilizing proteins for gel electrophoresis (typically used in SDS-PAGE sample buffer at 5% concentration). Also it reduces excess oxidative polymerization of catalysts. Cleaving intermolecular (between subunits) disulfide bonds allows the subunits of a protein to separate independently on SDS-PAGE. Cleaving intramolecular (within subunit) disulfide bonds allows the subunits to become completely denatured so that each peptide migrates according to its chain length with no influence due to secondary structure. In solution, 2-mercaptoethanol is readily oxidized in air to a disulfide, especially at alkaline pH. Because of this property, it is widely used to protect proteins, enzymes in particular, from becoming inactive. An excess of 2-mercaptoethanol (generally used at 0.01 M) will maintain the protein thiol groups in their reduced state.
