MES buffered saline is widely used in biological and biochemical research due to its ability to maintain a stable pH environment. It is particularly effective in cell culture applications, where it provides a consistent and non-toxic medium for cell growth and maintenance. The buffer is also utilized in protein purification processes, as it helps stabilize proteins and prevents denaturation during extraction and separation. Additionally, MES buffered saline is employed in electrophoresis techniques, ensuring optimal conditions for the separation of biomolecules like DNA, RNA, and proteins. Its compatibility with various experimental protocols makes it a versatile choice in laboratories.
