Formulated for running proteins on Bis-Tris gels, including Invitrogen's NuPAGE® and Bolt Bis-Tris gel. MOPS/SDS Running Buffer is preferred for separating medium- to large-sized proteins. Both MES SDS Running Buffer and MOPS SDS Running Buffer can be used with Bis-Tris gels. MES has a lower pKa than MOPS, making the MES SDS Running Buffer faster than the MOPS SDS running buffers. The difference in ion migration affects stacking and results in a difference in protein separation range between these buffers. Use of MOPS buffer allows proteins to run slower than when using MES buffer. MOPS buffer is preferred for separating medium- to large-sized proteins. MES buffer is preferred for separating small- to medium-sized proteins.Composition: Tris 50 mM, MOPS 50 mM, SDS 0.1%, EDTA 1 mM, pH 7.7. (Exact same composition as NuPage and Bolt 20xMOPS Running Buffers) Compatibility: Bis-Tris precast gels, including Bolt gels and NuPAGE gel Storage: 4°C recommended. Shelf-life: 6 months, when stored properly. MSDS Shelf-life: 6 months, when stored properly. MSDS
