Tris hydrochloride solution, pH 8.0 (CAS 1185-53-1 (solid))

Tris hydrochloride solution at pH 8.0 is another critical reagent used extensively in biochemical and molecular biology research. The solution′s pH is specifically set to 8.0 to suit a range of experimental conditions, particularly those where a slightly basic environment is required. This pH is especially pivotal in DNA replication and protein assays where it can impact the activity and stability of various enzymes. One of the primary applications of Tris hydrochloride solution pH 8.0 is in DNA extraction and purification protocols. At this pH, the solution helps maintain the integrity of the DNA while providing an optimal environment for enzymes such as DNA polymerase and restriction enzymes, which require a specific and stable pH for optimal activity. This is crucial for achieving high fidelity in techniques like PCR amplification and genetic cloning. Additionally, Tris hydrochloride at this pH is commonly used in the preparation of buffer solutions for Western blotting, a technique used to detect specific proteins in a sample. The buffer helps maintain a consistent pH during the transfer of proteins from a gel to a membrane, which is critical for the binding efficiency and specificity of antibodies used in the detection process. In protein crystallization, Tris hydrochloride pH 8.0 is used to create a conducive environment for protein stability and solubility, facilitating the formation of crystals. This is essential for structural studies using X-ray crystallography, which requires high-quality crystals to determine the three-dimensional structure of proteins. Thus, Tris hydrochloride at pH 8.0 serves as a versatile buffer in various research settings, ensuring biochemical reactions proceed under controlled and stable conditions, essential for reliable and reproducible results.
