MES monohydrate is widely used as a buffering agent in biochemical and molecular biology applications. It is particularly effective in maintaining a stable pH environment in cell culture media, enzyme assays, and protein purification processes. Its buffering capacity is optimal in the pH range of 5.5 to 6.7, making it suitable for experiments involving sensitive biological molecules. Additionally, MES monohydrate is often employed in electrophoresis and chromatography techniques to ensure consistent and reliable results. Its low UV absorbance also makes it a preferred choice in spectroscopic studies and analytical methods where minimal interference is required.
