Application of Bicine in the Preparation of Stable Substrate Solutions

The stability of substrate solutions is crucial for the accuracy of experimental results in biochemistry and molecular biology experiments. Among them, Bicine (N, N-di (hydroxyethyl) glycine) is highly favored as a biological buffer due to its excellent properties, playing an indispensable role in preparing stable substrate solutions. This article will discuss in detail the application of Bicine in the preparation of stable substrate solutions from multiple aspects.

The basic characteristics of Bicine

Bicine， Also known as N, N-di (hydroxyethyl) glycine, it is a zwitterionic buffer and belongs to the Good's buffer series. Its CAS number is 150-25-4, and its pH buffer range is between 7.6-9.0. As a biological buffer, Bicine is widely used in low-temperature biochemical work, especially in the preparation of stable substrate solutions.

Application of Bicine in the Preparation of Stable Substrate Solutions

1. Enzyme reaction buffer

In enzymatic reactions, enzymes act as biocatalysts and their activity is greatly influenced by pH values. Bicine, as an enzyme reaction buffer, can maintain pH stability within a certain range, providing a suitable environment for enzymatic reactions. Meanwhile, Bicine has strong buffering ability and can resist external acid-base interference, ensuring the stability of the substrate solution.

2. Serum guanine enzyme determination

In the experiment of serum guanine enzyme determination, the stability of the substrate solution is crucial for the accuracy of the measurement results. Bicine, as a biological buffer, can effectively stabilize substrate solutions and prevent them from changing during the measurement process. Meanwhile, Bicine can also interact with other components in the serum, improving the sensitivity and accuracy of the measurement.

3. Electrophoretic buffer

Electrophoresis buffer is an important part of nucleic acid and protein gel electrophoresis system, which is of great significance for maintaining a constant pH value of the electrophoresis system. Bicine, as an electrophoresis buffer, can provide a stable pH environment for biological macromolecules such as nucleic acids and proteins during the electrophoresis process, ensuring their stability during the electrophoresis process. In addition, Bicine's buffering ability can also resist external acid-base interference, ensuring the accuracy of electrophoresis results.

Preparation method of Bicine

The preparation method of Bicine is relatively simple, usually requiring the preparation of Bicine powder and deionized water. Firstly, dissolve Bicine powder in deionized water in a certain proportion to prepare a certain concentration of Bicine solution. Then, according to experimental needs, the pH value of Bicine solution can be adjusted by adding alkaline solutions such as NaOH. It should be noted that during the preparation process, factors such as temperature, stirring speed, and mixing ratio should be strictly controlled to ensure the quality and stability of Bicine solution.

conclusion

In summary, Bicine plays an important role as an excellent biological buffer in the preparation of stable substrate solutions. Its pH buffering ability and stability make it an ideal choice for enzymatic reactions, serum guanine enzyme determination, and electrophoresis buffer solutions. With the continuous deepening of research in biochemistry and molecular biology, the application prospects of Bicine will be even broader.
