TES buffer is widely used in biochemical and molecular biology applications due to its effective buffering capacity in the pH range of 6.8 to 8.2. It is commonly employed in protein purification processes, particularly in chromatography techniques, where maintaining a stable pH is crucial for preserving protein structure and function. TES buffer is also utilized in enzyme assays and cell culture media to ensure optimal conditions for enzymatic activity and cell growth. Additionally, it serves as a buffer in electrophoresis and other analytical techniques, providing a stable environment for accurate separation and analysis of biomolecules. Its compatibility with various biological systems makes it a versatile choice for maintaining pH stability in diverse experimental setups.
