When it comes to biochemical experiments, especially in the field of protein separation and purification, the role of biological buffers cannot be underestimated. A high-quality buffer solution can exhibit strong capabilities in the presence of trace amounts of acid or alkali, as well as the addition of water, greatly suppressing pH fluctuations and creating a stable chemical environment for experiments. This ability is mainly attributed to its unique composition, such as a mixed solution of weak acids and their salts (such as acetic acid HOAc and sodium acetate NaOAc) or a mixed solution of weak bases and their salts (such as ammonia NH3 · H2O and ammonium chloride NH4Cl), which together form what we call a buffer.
The role of buffer is crucial in the separation and purification process of proteins. The purification of proteins is a complex and delicate task, as each protein has its unique properties and requires specific purification methods. In this process, the stability of proteins often depends on the multi-component buffer system used. A good buffer system can not only maintain the solubility of proteins during the experimental process, but more importantly, it can provide the most suitable environment for proteins without damaging their biological activity.
We know that the purification process of most proteins is carried out in vitro, which means they are detached from their original physiological environment. Therefore, the buffer systems corresponding to recombinant proteins in the market are particularly important. These buffer systems can simulate the environment of natural proteins in the body, providing the possibility for stable storage and transportation of proteins.
When choosing and using buffer solutions, we must consider several key factors. Firstly, the composition of the buffer solution. Ideally, the components of the buffer should not interact with proteins in any form as this may affect their function. For example, some enzymes may be inhibited by phosphate groups in phosphate buffer, leading to their loss of function. Therefore, when choosing a buffer, we should try to choose components that are well compatible with proteins and refer to the recommendations in relevant manuals.
In addition, the pH value of the buffer solution is also an important consideration factor. The choice of pH value depends on the actual application of the protein. If proteins are used for biological assays such as enzyme assays, we should choose the pH values that enable enzymes to exhibit optimal activity. When preparing proteins for purification technology, we need to choose an appropriate pH value based on experimental conditions to ensure maximum purification efficiency. Of course, in situations where a specific pH value is not required, we should choose pH values that can enable proteins to exhibit optimal stability.
