The utility model provides a centrifugal device for cell protein detection relates to cell protein detection field, including centrifugal unit, including the outer cover, the inner chamber of setting in the outer cover, the inner chamber of setting in the inner chamber of the cover that is connected in the outer cover top through the hinge activity, centrifugal assembly for carrying out centrifugal operation of setting in the inner chamber of the inner chamber of the inner chamber of setting, and the microcontroller of setting in the outer cover front, temperature control unit, including the base, the radiating fan of setting in the base inner chamber one side, the utility model discloses through temperature sensor real -time monitoring the temperature in the inner chamber cavity, and cooperate microcontroller can make the synergistic operation of semiconductor refrigerating sheet and radiating fan, can rapidly reduce and maintain the temperature in the inner chamber cavity, ensure that the protein sample keeps stable biological activity in the centrifugal process, through centrifugal assembly makes cell fragments, cell organ and so on solid particle and protein solution can more effectively separate, has improved the purity of protein.

The present application provides a Cistanche deserticola polysaccharide and Hippophae rhamnoides polypeptide composition with hypoxia tolerance activity, and the amino acid sequence of the Hippophae rhamnoides polypeptide is SEQ ID NO:1. The composition provided by the present application can significantly prolong the survival time of mice, is superior to single components and positive controls, and exhibits synergistic effect. Molecular docking analysis shows that the used polypeptide has high affinity with SIRT1, supporting its mechanism in optimizing cell energy metabolism and antioxidant stress. The composition is suitable for highland medical protection and adjuvant treatment of hypoxic diseases, and has the advantages of clear components and stable biological activity.
