MES solution (CAS 4432-31-9)

MES (2-(N-morpholino)ethanesulfonic acid) solution is a critical reagent utilized in various biochemical and molecular biology experiments. This compound is a zwitterionic buffer with a pKa near physiological pH, making it an ideal choice for maintaining a stable pH environment in biological assays. One of the primary uses of MES solution is in electrophoresis techniques, such as SDS-PAGE (sodium dodecyl sulfate-polyacrylamide gel electrophoresis). MES buffer provides a stable pH environment during protein separation, ensuring accurate migration of proteins through the gel matrix. Moreover, MES solution is commonly used in protein biochemistry experiments, including enzyme assays and protein purification processes. Its buffering capacity helps maintain the activity and stability of enzymes and proteins under physiological conditions, making it valuable in biochemical research. Additionally, MES solution finds applications in molecular biology protocols, such as nucleic acid electrophoresis and nucleic acid hybridization assays. Its low UV absorbance and minimal fluorescence make it suitable for use in nucleic acid visualization techniques. Furthermore, MES solution is utilized in cell culture media formulations to maintain a consistent pH during cell culture experiments. Its compatibility with mammalian cell lines and minimal impact on cell viability make it a preferred choice for maintaining physiological conditions in vitro.
