Application

BME es idóneo para reducir los puentes disulfuro de las proteínas antes de la electroforesis en gel de poliacrilamida y suele incluirse en un tampón de muestra para SDS-PAGE a una concentración de un 5 %. La escisión de los puentes disulfuro intermoleculares (entre subunidades) permite que las subunidades de una proteína se separen de forma independiente en la SDS-PAGE. La escisión de los puentes disulfuro intramoleculares (dentro de la subunidad) permite la desnaturalización completa de las subunidades para que cada péptido migre en función de la longitud de su cadena sin influencia de la estructura secundaria.
