4-Morpholineethanesulfonic acid

Description:
4-Morpholineethanesulfonic acid, commonly referred to as MES, is a zwitterionic buffer widely used in biological and biochemical research. It has a molecular formula of C6H13NO3S and features a morpholine ring, which contributes to its solubility in water and stability across a range of pH levels. MES is particularly effective in maintaining a stable pH in the physiological range, typically between pH 6.0 and 7.5, making it suitable for various applications, including cell culture and enzyme assays. The sulfonic acid group enhances its buffering capacity, while the morpholine structure provides a neutral charge at physiological pH, minimizing interference in biological systems. MES is generally considered non-toxic and is compatible with many biological molecules, which makes it a preferred choice for experiments involving proteins and nucleic acids. Additionally, it is stable under a variety of conditions, although it should be stored properly to prevent degradation. Overall, MES is a versatile and reliable buffer in laboratory settings.
