Synonym(s): 2-(N-Morpholino)ethanesulfonic acid sodium salt, 4-Morpholineethanesulfonic acid sodium salt, MES, Sodium Salt
Description
MES-Na (2-Morpholinoethanesulfonic Acid Sodium Salt) is a high-purity (≥99.0%) biochemical-grade buffer widely used in biological and biochemical research. It dissolves easily in water to form a clear, transparent solution and provides stable buffering in the mildly acidic pH range. With low metal-ion binding and minimal interference in enzyme-based assays, MES-Na is well-suited for applications requiring precise pH control. Its stability, clarity, and compatibility with sensitive proteins and enzymes make it a reliable component in many laboratory workflows.
