General description

A disulfide-reducing agent.
A disulfide-reducing agent. Reagent commonly used in organic synthesis (aborsorbance: ≤1.50 at 260 nm; ≤0.31 at 280 nm).

Application

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.
