Message: | The structure and function of the protein need to be maintained in a suitable pH environment. Therefore, the choice of pH buffer is very important during the preparation and purification of the protein. Only a suitable buffer can ensure the activity and structural stability of the protein.
Effect of buffer in protein purification process
The buffer in the protein purification process should not only prevent protein degradation, but also prevent protein aggregation, which has a significant impact on the experimental results. The following factors should be considered when selecting and reagent buffers: pH, buffer system, salt ions, reducing agents and stabilizers. Each of these factors should be optimized according to the purified target protein, and the activity of the target protein should be used as an evaluation criterion for optimization.
Understand protein stability conditions
Commonly used buffers in the protein purification process include Tris, Tricine, Bis-Tris, MOPS, etc. Among
Now the adaptation pH value, isoelectric point, and buffer range of the buffer to be purified can be found, and you can directly match it according to the corresponding requirements. Desheng is a manufacturer of in vitro diagnostic reagents, which can provide large-package pH buffers such as Tris, MOPS, Bicine, etc.
