Molecular Structure:

Product description: Buffer plays a crucial role in biochemical and molecular biology experiments, as it can stabilize the pH value of the cell environment, maintain enzyme activity, and protect the stability of biological macromolecules. Among numerous buffer solutions, 1,3-bis ((trihydroxymethyl) methylamino) propane (Bis Tris) is highly favored by researchers due to its unique properties. PH range of Bis Tris propane buffer Bis Tris propane buffer is a binary buffer system with two pKa values of varying sizes, with a primary acid dissociation constant Pka1=6.8 and a secondary acid dissociation constant Pka2=9.0. At room temperature, the working pH range of Bis-Tris propane buffer is 6.3-9.5. Within this range, Bis-Tris propane buffer can effectively maintain the stability of the solution and has a good protective effect on the stability of most biological macromolecules. Advantages of Bis Tris Propane Buffer (1) Excellent buffering ability: The pKa value of Bis-Tris propane buffer solution is close to the neutral pH value, therefore it has extremely strong buffering ability under neutral conditions. It can effectively resist the influence of external acidic and alkaline substances on the pH value of the solution, and maintain the stability of the solution. (2) Low background signal: In experiments such as electrophoresis and immunoblotting, it exhibits the characteristic of low background signal, which is conducive to accurately detecting the signal of target proteins and improving the reliability of experimental results. (3) Protection of protein stability: Bis Tris propane buffer has a good stability protection effect on many proteins, which can maintain the natural conformation and function of proteins. Application of Bis-Tris Propane Buffer Bis-Tris propane buffer is widely used in various experiments in the fields of biochemistry and molecular biology, including: (1) Protein electrophoresis: commonly used in SDS-PAGE and Native-PAGE electrophoresis experiments to separate proteins and detect their relative molecular weight. (2) Immunoblotting: Bis-Tris propane buffer is used as a protein transport buffer for immunoblotting experiments to detect the expression level of target proteins. (3) Cell culture: Bis-Tris propane buffer can be used for the preparation of cell culture medium to maintain a stable pH value during the cell culture process. (4) Nucleic acid electrophoresis: suitable for DNA and RNA electrophoresis experiments to detect the length and concentration of target nucleic acids.
