MES (2-(N-morpholino) ethanesulfonic acid) is a widely used zwitterionic buffering agent belonging to the Good’s buffer family, designed to maintain stable pH conditions in biochemical and molecular biology applications.

Description

MES (2-(N-morpholino) ethanesulfonic acid) is a widely used zwitterionic buffering agent belonging to the Good’s buffer family, designed to maintain stable pH conditions in biochemical and molecular biology applications. With an effective buffering range of pH 5.5–6.7, MES is particularly suited for experiments requiring mildly acidic conditions, including enzyme assays, protein purification, and cell-based studies.

Proteogenixx’s MES Buffer Grade is manufactured to high purity standards, ensuring minimal interference with sensitive biological reactions. Its excellent solubility and chemical stability allow for easy preparation of precise buffer solutions, while its low metal-binding capacity and minimal UV absorbance make it ideal for spectrophotometric and enzymatic applications.

MES is commonly used in protein chemistry, chromatography buffers, plant biology studies, and various in vitro biochemical assays where reliable pH control is critical. Its robust buffering performance supports experimental reproducibility and consistent results across diverse laboratory workflows.

Storage: Store tightly sealed at room temperature in a dry environment to maintain long-term stability.
