DETAILS

Description (English)

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.

Description (简体中文)

Application
BME 用于在聚丙烯酰胺凝胶电泳前还原蛋白质二硫键，通常以 5% 的浓度包含在用于 SDS-PAGE 的样本缓冲液中。裂解分子间（亚基之间）的二硫键，从而使蛋白质亚基在 SDS-PAGE 上各自分开。裂解分子内（亚基内）的二硫键从而使亚基完全变性，以便每个肽按照其链长迁移而不受二级结构的影响。
