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, such as ELISA, to ensure consistent pH levels during antibody-antigen interactions. It is also used in chromatography as a mobile phase component to enhance separation efficiency. In histology, borate buffer helps in tissue fixation and staining processes. Furthermore, it serves as a stabilizing agent in various diagnostic kits and reagents, ensuring reliable performance in clinical and research settings.
