description Product Description
BES is widely used as a buffering agent in biochemical and biological research. It is particularly effective in maintaining stable pH levels in cell culture media, enzyme assays, and protein purification processes. Its buffering capacity is optimal in the pH range of 6.5 to 7.5, making it suitable for experiments involving biological systems that require neutral pH conditions. Additionally, BES is often employed in electrophoresis and chromatography techniques to ensure consistent and reliable results. Its low toxicity and minimal interference with biological processes make it a preferred choice in various laboratory applications.
