Protein separation technology with decanter centrifuge ultra-fast centrifuge

Protein is the material basis of life, is the organic macromolecule, is the basic organic matter that constitutes the cell, is the main bearer of life activities. Without protein there would be no life. Amino acids are the basic building blocks of proteins. It is a substance closely associated with life and with all forms of life activity.
With the development of science and technology, the application field of protein is also more and more, followed by the separation and purification of organic macromolecules of protein, including desalination and removal of small molecular impurities, heat source material, solution concentration and so on.
Protein separation and purification technology is the core technology in contemporary biological industry. The technical difficulty and cost are high; For example, 75% of the cost of a biologic drug is spent on downstream protein separation and purification.
And our common technology can be generally divided into the following: 1. Precipitation; 2. Electrophoresis; 3. Dialysis; 4. Chromatography; 5. Ultracentrifugation.
Now let's take a closer look at the fifth technique, ultracentrifugation.
Ultrafiltration method can also be called ultrafiltration method, which is a technology for separation according to the difference in the size of protein molecules, it uses high pressure or centrifugal force to force water and other small solute molecules through the semi-permeable membrane, while the protein remains on the membrane, and the filter membrane with different pore sizes can be selected to retain proteins of different molecular weights. It is one of the most commonly used separation methods today.
