BES Buffer is widely used in biochemical and molecular biology research due to its effective buffering capacity in the pH range of 6.4 to 7.8. It is commonly employed in cell culture applications to maintain a stable pH environment, which is crucial for cell growth and viability. BES Buffer is also utilized in electrophoresis techniques, particularly for DNA and RNA separation, as it provides consistent pH control during the process. Additionally, it serves as a buffering agent in protein purification and crystallization experiments, ensuring optimal conditions for protein stability. Its compatibility with various biochemical assays and its low toxicity make it a preferred choice in laboratory settings.
