Tris-MES-SDS

Tris-MES-SDS (hereinafter referred to as MES) appears as white to off-white instant granules. Each pouch makes 1 L of 1x MES solution conveniently with a simple procedure. MES is composed of Tris, MES, EDTA and SDS. 1x MES contains 50 mM Tris, 50 mM MES, 1 mM EDTA and 0.1% SDS. MES buffer is a protein gel electrophoresis buffer commonly used in biology labs that is suitable for normal SDS-PAGE of proteins. It is especially good for SDS-PAGE with the Bis-Tris buffer system. With Bis-Tris based protein gels, it provides good electrophoresis results of small to medium molecular weight proteins.
