TE Buffer is widely used in molecular biology for the storage and dilution of DNA and RNA. It helps maintain the stability of nucleic acids by providing a suitable pH environment and chelating metal ions that could degrade DNA. It is commonly employed in gel electrophoresis, DNA extraction, and PCR protocols to ensure the integrity of genetic material during experimental procedures. Additionally, TE Buffer is used in the preparation of samples for sequencing and other analytical techniques, making it a staple in laboratories focused on genetic research.
