Our comprehensive portfolio of upstream process chemicals not only provides biopharmaceutical manufacturers with high-quality raw materials for production of classical and novel therapies, but also helps them get to market faster and simplify regulatory challenges. Trust us to deliver supply chain transparency and reliable sourcing around the globe, streamlining your product qualification with best-in-class regulatory support and service.

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.
