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).

Packaging

250 ml in Metal can

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.

Warning

Toxicity: Toxic (F)
