Carbonate Buffered Saline is widely used in biological and medical research as a buffer solution to maintain a stable pH environment. It is particularly effective in cell culture applications, where it helps to keep the pH level consistent, ensuring optimal conditions for cell growth and viability. This solution is also commonly employed in immunohistochemistry and other staining procedures to wash and prepare tissue samples without altering their pH. Additionally, it is utilized in various diagnostic assays and biochemical experiments to provide a reliable medium for reactions that are sensitive to pH changes. Its buffering capacity makes it suitable for use in maintaining the stability of biological samples during storage and transportation.
