Sodium borate buffer is widely used in molecular biology and biochemistry for maintaining stable pH levels in various experimental procedures. It is particularly effective in DNA and RNA electrophoresis, where it helps to ensure consistent migration of nucleic acids through gels. The buffer is also utilized in protein analysis, including Western blotting, to maintain optimal conditions for antibody binding and detection. In addition, sodium borate buffer is employed in enzyme assays and other biochemical reactions where precise pH control is critical for accurate results. Its buffering capacity makes it a reliable choice for a range of laboratory applications requiring stable pH environments.
