[0026] In this embodiment, a groove matching the measuring cup 4 is provided on the top of the workbench 1. An optimized culture medium is provided inside the measuring cup 4. The culture medium components inside the measuring cup 4 include: aluminum chloride, biotin, calcium pantothenate, choline chloride, cobalt chloride, copper sulfate, glucose, ethanolamine, ferric citrate, folic acid, glutathione, 4-hydroxyethylpiperazineethanesulfonic acid, inositol, arginine, asparagine, aspartic acid, cysteine, glutamic acid, histidine hydrochloride, hydroxyproline, isoleucine, leucine, lysine, methionine, phenylalanine, proline, serine, threonine, tryptophan, tyrosine, valine, magnesium chloride, manganese chloride, nicotinamide, Pluronic F68, potassium chloride, potassium iodide, putrescine, thiamine, vitamin B2, sodium chloride, disodium hydrogen phosphate, sodium pyruvate, spermine, vitamin B1, vitamin B12, and zinc chloride. The measuring cup 4 is embedded in the groove on the top of the workbench 1, and the culture medium is mixed into a liquid. After the mixing is completed.
[0027] In this embodiment, the fixed column 10 is set away from the center of the disk 9, and the diameter of the disk 9 is consistent with the inner diameter of the measuring cup 4. The servo motor 8 is started. Since the disk 9 is fixedly connected to the output end of the servo motor 8, when the servo motor 8 is started, its output end will drive the disk 9 to rotate together. At this time, the fixed column 10 fixedly connected to the disk 9 will then drive the stirring rod 11 to make a circular motion around the center of the disk 9 through the fixing bolt 12, thereby achieving the purpose of stirring.
[0028] In this embodiment, a circular groove matching the stirring rod 11 is provided at the bottom of the fixing column 10, and a fixing groove matching the fixing bolt 12 is provided on the surface of the fixing column 10 and the surface of the stirring rod 11.

Compared with other serum-free culture media, the culture medium with added CM01 can achieve a better doubling rate, a higher peak density, and a better cell state. Example 2
[0030] On the basis of Example 1, a preferred embodiment of a high-efficiency culture medium provided by the present invention is as follows Figures 1 to 5 As shown: the fixing mechanism 3 includes a threaded rod 31, a slider 32, a transmission plate 33, a transmission rod 34 and a fixed plate 35. The surface of the threaded rod 31 is threadedly connected to the slider 32, the top of the slider 32 is rotatably connected to the transmission plate 33, the top of the transmission plate 33 is rotatably connected to the transmission rod 34, and the surface of the transmission rod 34 is fixedly connected to the fixed plate 35.
[0031] In this embodiment, two groups of transmission plates 33, transmission rods 34 and fixed plates 35 are respectively provided. The transmission plates 33 are arranged at an angle, and the fixed plates 35 are arranged in a semicircular ring shape. Because the slider 32 is engaged with the threaded rod 31, when the threaded rod 31 rotates, it will drive the slider 32 to slide backward along the inner wall of the slide groove at the top of the workbench 1. At this time, the two groups of transmission plates 33 rotationally connected to the slider 32 will swing left and right relative to each other.
[0032] In this embodiment, two groups of transversely arranged sliding grooves are provided on the top of the workbench 1, and the two groups of transmission rods 34 respectively penetrate the tops of the two groups of transmission plates 33 and are embedded in the two groups of transverse grooves on the top of the workbench 1. Because the two groups of transmission rods 34 are respectively rotatably connected to the two groups of transmission plates 33, and the two groups of transmission rods 34 respectively penetrate the tops of the two groups of transmission plates 33 and are embedded in the two groups of transverse grooves on the top of the workbench 1, when the transmission plates 33 swing relative to each other, the two groups of transmission rods 34 will be driven to slide relative to each other in the two groups of transverse grooves on the top of the workbench 1 and approach each other. At this time, the two groups of fixed plates 35 fixedly connected to the two groups of transmission rods 34 will move relative to each other and approach each other. When the two groups of fixed plates 35 move until they are completely in contact with the measuring cup 4, the measuring cup 4 can be fixed.
[0033] The working principle and usage process of the present invention are as follows: First, the stirring rod 11 is inserted into the circular groove at the bottom of the fixed column 10 so that the fixing groove on the surface of the stirring rod 11 corresponds to the fixing groove on the surface of the fixed column 10, and then the fixing bolt 12 is passed through the fixing grooves on the surfaces of the fixed column 10 and the stirring rod 11, and the fixing bolt 12 is tightened to connect the stirring rod 11 to the fixed column 10. Subsequently, the culture medium is poured into the interior of the measuring cup 4, and then the measuring cup 4 is inserted into the groove on the top of the workbench 1. At this time, the threaded rod 31 is manually controlled to rotate counterclockwise. Because the slider 32 is engaged with the threaded rod 31, when the threaded rod 31 rotates, it will drive the slider 32 to slide backward along the inner wall of the slide groove on the top of the workbench 1. At this time, the two sets of transmission plates 33 rotatably connected to the slider 32 will swing left and right relative to each other, because the two sets of transmission rods 34 are respectively rotatably connected to the two sets of transmission plates 33, and the two sets of transmission rods 34 respectively pass through the top of the two sets of transmission plates 33 and are embedded in the two sets of horizontal grooves on the top of the workbench 1, so when the transmission When the movable plate 33 swings relative to each other, it will drive the two sets of transmission rods 34 to slide relative to each other in the two sets of horizontal grooves on the top of the workbench 1 and approach each other. At this time, the two sets of fixed plates 35 fixedly connected to the two sets of transmission rods 34 will move relative to each other and approach each other. When the two sets of fixed plates 35 move to completely fit with the measuring cup 4, the measuring cup 4 can be fixed. Subsequently, the electric telescopic rod 6 is started to drive the lifting plate 7 to descend. At this time, the lifting plate 7 will drive the servo motor 8, the disc 9 and the fixed column 10 to descend together, thereby driving the stirring rod 11 to descend into the inside of the measuring cup 4. Then, the servo motor 8 is started. Because the disc 9 is fixedly connected to the output end of the servo motor 8, when the servo motor 8 is started, its output end will drive the disc 9 to rotate together. At this time, the fixed column 10 fixedly connected to the disc 9 will drive the stirring rod 11 to make a circular motion around the center of the disc 9 through the fixing bolt 12, thereby achieving the purpose of stirring, thereby replacing manual stirring to ensure the uniformity of the culture medium liquid mixing and improving work efficiency.
[0034] After mixing, the mixture was filtered through a Corning 0.22 μm filter and poured into shake flask 16. 2 g / LC CM01 was added and the specific ingredients were then labeled. CM01 maintained the highest viable cell density and the best viability. Compared with the initial serum-free medium, the suspension growth performance of PK15 cells was greatly improved. Compared with the previous serum-based medium, the medium supplemented with CM01 can eliminate the cells' dependence on serum. Compared with other serum-free media, the medium supplemented with CM01 can achieve a faster doubling rate, higher peak density, and better cell status.
[0035] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
