Biological buffer DIPSO (68399-80-4) detailed description for quick understanding

In the research fields of biochemistry and molecular biology, buffering agents can maintain the pH stability of reaction systems and provide a suitable environment for various biochemical reactions. As a unique biological buffer, understanding its characteristics, buffering performance, application fields, and limitations can help researchers accurately select and use DIPSO in experiments, fully leverage its advantages, and provide stable and reliable experimental conditions for biological research.

Basic characteristics of DIPSO

The Chinese name for DIPSO is 3- [N, N-di (hydroxyethyl) amino] -2-hydroxypropanesulfonic acid, also known as 3-bis (2-hydroxyethyl) amino-2-hydroxypropanesulfonic acid. From its molecular structure, it belongs to the dipole ion buffering agent and contains dihydroxyethylamine, which makes it biologically classified as a member of the bis (2-hydroxyethylamine) amine family of buffering agents.

DIPSO appears as a white crystalline powder, and its notable feature is that it is almost insoluble in organic solvents involved in biochemical reactions, and its solubility does not change with temperature. In an aqueous solution at 20 ℃, the saturation is 0.1M, and the colorless and transparent solution formed at this time is acidic.

The buffering performance of DIPSO

After dissolving DIPSO into a buffer solution, it can effectively adjust the pH of the solution within the range of 7.0-8.2. This pH range is suitable for many biochemical reactions and experiments, such as the activity determination of certain enzymes. Within this pH range, enzymes can maintain high activity, ensuring the accuracy of experimental results.

As a dipole ion buffer, DIPSO can resist external acid-base interference in solution through its own ionization equilibrium, thereby maintaining the stability of the solution pH. When acidic substances are added to the solution, the alkaline groups in DIPSO molecules will bind with hydrogen ions, inhibiting the decrease in pH value; When alkaline substances are added, their acidic groups release hydrogen ions, preventing an increase in pH.

Application areas of DIPSO

1. Protein Separation and Purification

In experiments using chromatography to separate and purify proteins, changes in pH can affect ionizable compounds, thereby interfering with the separation efficiency of proteins. DIPSO buffer can maintain the acidity and alkalinity of the system at a relatively constant value, effectively avoiding this interference. For example, in ion exchange chromatography, a stable pH environment facilitates specific binding and elution between proteins and ion exchange resins, thereby improving the purity and efficiency of protein separation.

2. Electrophoretic technique

Electrophoresis technology is one of the commonly used analytical methods in biochemistry and molecular biology. During electrophoresis, DIPSO buffer plays a crucial role. On the one hand, it can maintain the pH value of the solution unchanged when current passes through the experimental substance, ensuring the stability of the charged properties of biomolecules and thus ensuring the repeatability of their migration behavior in an electric field; On the other hand, DIPSO buffer also provides the necessary ions for migration in electrophoresis experiments, promoting the movement of biomolecules in an electric field and enabling effective separation of different biomolecules based on their charge and size characteristics.

Other precautions when using DIPSO

DIPSO can form complexes with various metals and precipitate, which makes it unsuitable for biological research environments that require metal ions. For example, in cell culture media that require metal cations, using DIPSO to stabilize the pH value can lead to the precipitation of metal ions, thereby affecting the normal growth and metabolism of cells. Although DIPSO has good buffering performance within a certain pH range, it cannot meet the requirements for experiments that require extremely strict pH values and exceed its effective buffering range. In certain biochemical reactions under extreme acidic or alkaline conditions, it is necessary to choose other more suitable buffering agents.
