WebNov 21, 2024 · What is the function of Tris in DNA extraction? During extraction from any number of sources, DNA is pH sensitive. During cell lysis, removal of unwanted cellular components and precipitation, tris is used to maintain a stable pH. Additionally, it plays a particularly important role in cell lysis. Why is a tris buffer important to science? WebTAE buffer is a buffer solution containing a mixture of Tris base, acetic acid and EDTA. In molecular biology it is used in agarose electrophoresis typically for the separation of nucleic acids such as DNA and RNA. [1] It is made up of Tris-acetate buffer, usually at pH 8.3, and EDTA, which sequesters divalent cations.
