CAPSO Sodium Salt is widely used as a biological buffer in various biochemical and molecular biology applications. It is particularly effective in maintaining stable pH levels in cell culture media, enzyme assays, and protein purification processes. Its zwitterionic nature allows it to function effectively in a wide pH range, making it suitable for use in electrophoresis and chromatography techniques. Additionally, CAPSO Sodium Salt is often employed in studies involving membrane proteins and lipid bilayers due to its ability to stabilize these structures without interfering with their function. It is also utilized in diagnostic kits and research studies where precise pH control is critical for accurate results.
