AMPSO sodium salt is widely used as a buffering agent in biochemical and molecular biology research. It is particularly effective in maintaining stable pH conditions in various experimental setups, especially in the pH range of 8.3 to 9.7. This makes it suitable for applications such as enzyme assays, protein purification, and cell culture studies where precise pH control is critical. Additionally, it is utilized in electrophoresis and chromatography techniques to ensure consistent and reliable results. Its low toxicity and compatibility with biological systems further enhance its utility in life science research.
