TE buffer (Tris-EDTA)

TE buffer, which contains Tris and EDTA, is a solution used in laboratories to preserve and handle DNA samples. Tris helps maintain a stable pH, keeping the DNA from breaking down due to acidity or alkalinity. EDTA binds to metal ions that could otherwise damage or degrade DNA molecules. Together, these components protect DNA from enzymatic activity and environmental factors, ensuring it remains intact for analysis or other scientific processes. TE buffer is a fundamental tool for storing DNA in research, diagnostics, and molecular biology applications.
