Tris acetate salt (CAS 6850-28-8)

Tris acetate salt, a derivative of tris(hydroxymethyl)aminomethane combined with acetic acid, serves as a crucial buffering agent in biochemical and molecular biology research. Noted for its effective buffering capacity in the slightly acidic to neutral pH range, tris acetate is extensively used in DNA and RNA gel electrophoresis, where it forms part of the electrophoresis buffer system—often alongside EDTA—to maintain a consistent pH and facilitate the efficient migration of nucleic acids through gels. This buffer is particularly valued for its gentle properties which minimize damage to biological molecules, making it suitable for enzyme assays and protein purification processes. In these applications, tris acetate helps stabilize enzyme activity by maintaining optimal pH conditions and supports protein solubilization and stabilization, critical for detailed protein analysis. The compound′s ability to provide a stable environment for a variety of biochemical reactions makes it indispensable in settings where precise pH control is essential, enhancing both the accuracy and reproducibility of experimental results in research laboratories focused on molecular biology and biochemistry.
