Highly purifying a certain biological macromolecule generally requires multiple methods, processes and constant changes of various external conditions to reach the intention. Usually, various methods are combined based on detailed objects. If they are removed, the difficulty of crystallizing unstable proteins will increase. The common sense touches on physics, chemistry, and biology.

Preservation activity avoids denaturation and degradation. In order to obtain natural protein, try to use gentle techniques, such as neutral, low temperature, avoid foaming, etc. Production line project: Bright Beer Tank Animal bone collagen extraction and refining equipment-Chinese medicine extraction and concentration production line-non-standard precision chemical equipment-microbial fermentation system' and other production line equipment, supply turnkey projects.　

Secondly, before separation and purification operations, it is often necessary to establish corresponding analysis and judgment methods to correctly guide the smooth progress of the entire separation and purification operations. Therefore, the selection conditions should be very gentle.

On the other hand, protein often exists in the way of combining with other biological substances, so it is also easy to combine with these substances, which brings difficulties to separation and purification.; the second is to place the mixture in a single phase, and through the effect of the physical force field, the components are distributed in different areas to achieve the intention of separation, such as electrophoresis , Ultracentrifugation, ultrafiltration, etc.

Welcome to call to discuss cooperation. Therefore, sufficient investigation and research should be carried out before the experiment, and relevant literature and materials should be consulted, and the physical, chemical and biological properties of the substance to be purified should be understood first, and then the experiment should be carried out. When creatively purifying a sample that does not know its structure and properties, it is more necessary to compare and explore various methods to find some operating rules and achieve expected results.), concentrated, dried and stored.
