Tris-EDTA Buffer pH7.4 (BZ230)

Tris-EDTA Buffer pH7.4 (BZ230)



Product Introduction 

TE stands for Tris-EDTA buffer, also known as T10E1 buffer. It is a commonly used buffer solution in molecular biology, especially when it involves DNA and RNA to protect it from degradation. TE buffer is composed of two reagents: Tris (the most commonly used pH buffer) and EDTA (divalent metal ion chelating agent). The pH buffer range of the former is 7.5-8.5. Under this environment, nuclease activity is low; The latter further inactivates the nuclease by chelating metal ions necessary for the nuclease.

This product is a ready-to-use 1×TE buffer, pH 7.4, autoclaved, does not contain DNase enzyme, suitable for DNA purification and storage. It can also be used as a washing buffer.

Product properties 1×TE working solution contains 10 mM Tris-HCl and 1 mM EDTA·Na2, pH 7.4

TE buffer is a commonly used buffer solution in molecular biology, especially in procedures involving DNA, cDNA or RNA. “TE” is derived from its components: Tris, a common pH buffer, and EDTA, a molecule that chelates cations like Mg2+. The purpose of TE buffer is to solubilize DNA or RNA, while protecting it from degradation.

Tris buffer solutions are widely used in cell and molecular biology for processes such as protein and nucleic acid extraction and purification. Tris-EDTA (TE) buffer solution, pH 8.0 may also be used as a washing buffer.
