Borate buffer is widely used in biochemical and molecular biology applications due to its ability to maintain a stable pH. It is commonly employed in electrophoresis, particularly for DNA and RNA separation, as it provides optimal conditions for nucleic acid migration. Additionally, borate buffer is utilized in immunoassays and protein studies, where it helps maintain the integrity of biomolecules. It is also used in chromatography as a mobile phase component to enhance separation efficiency. In diagnostic kits, borate buffer ensures consistent performance by stabilizing pH-sensitive reagents. Its compatibility with various enzymes and proteins makes it a versatile choice in laboratory research and diagnostic applications.
