Borate buffer is widely used in biochemical and molecular biology applications due to its effective buffering capacity in the pH range of 8.0 to 10.0. It is commonly employed in electrophoresis, particularly for DNA and RNA separation, as it maintains a stable pH environment during the process. In immunoassays, borate buffer helps in maintaining the optimal conditions for antibody-antigen interactions. It is also utilized in the preparation of staining solutions for microscopy and as a component in various diagnostic kits. Additionally, borate buffer plays a role in the stabilization of enzymes and proteins in research and industrial applications. Its compatibility with many chemical reagents makes it a versatile choice in laboratory settings.
