TE Buffer is widely used in molecular biology for the storage and dilution of DNA and RNA. It helps maintain the stability and integrity of nucleic acids by providing a suitable pH environment and chelating metal ions that could degrade the samples. It is commonly utilized in procedures such as gel electrophoresis, PCR, and DNA extraction. Additionally, TE Buffer is essential for resuspending DNA pellets after precipitation and for long-term storage of DNA at -20°C or -80°C to prevent degradation. Its consistent pH and ionic strength make it a reliable choice for various laboratory applications involving nucleic acids.
