• 2-mercaptoethanol is a thiol compound, commonly used as a reducing agent in organic reactions.bme is suitable for reducing protein disulfide bonds prior to polyacrylamide gel electrophoresis and is usually included in a sample buffer for sds-page at a concentration of 5%
• 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
