Tris-EDTA Buffer, TE (pH 8.0, Low Endotoxin)

The Tris-EDTA (TE) Buffer is a commonly used buffer solution in molecular biology, especially in processes involving nucleic acids. This buffer is composed of a 1X concentration of Tris, a buffering agent, and EDTA, which has the ability to prevent degradation of DNA and RNA by chelating magnesium or other divalent metal ions, and allows pH regulation within the range of 7.5-8.5. It is widely used often for DNA and RNA gel electrophoresis, and also for DNA automated sequencing.
