This 1 M Tris‑Base solution serves as a strong alkaline buffer, widely used in biochemical and molecular biology applications. With an effective buffering range of pH 7.0–9.0, it provides excellent pH stability for DNA and RNA purification, in situ hybridization, and protein extraction. Its high pH (> 10) formulation makes it particularly useful as a stock solution for preparing working buffers and gels for electrophoresis, including both agarose and polyacrylamide systems. Additionally, it functions as a robust wash buffer in Western blotting protocols where precise pH adjustment is required.
