Embodiment 1
[0041] The cell screening method based on immunomagnetic bead labeling of the present invention includes, as figure 1 As shown in the cell screening device, the cell screening device includes a hollow cuboid shell, and a layer of cell sieves is arranged horizontally inside the shell to divide the shell into an upper cavity and a lower cavity, and the cavity is filled with phosphate buffer saline PBS . The left side of the cell screening device is provided with a sample inlet corresponding to the lower cavity; the right side of the cell screening device is respectively provided with an upper sample outlet and a lower sample outlet corresponding to the upper cavity and the lower cavity.
[0042] In this embodiment, setting the housing of the cell screening device in the shape of a cuboid is only a preferred form. Of course, the housing of the cell screening device can be in a regular shape such as a cylinder, a cube, or any irregular shape. Those skilled in the art can make spe...
Embodiment 2
[0061] The difference between embodiment 2 and embodiment 1 is that in this embodiment, transverse oscillation microwaves are selected for transverse oscillation, which are generated by microwave generators. Under the force of transverse microwave, the immunomagnetic beads shake slightly, and the speed and pass rate of the immunomagnetic beads passing through the cell sieve are very high.
Embodiment 3
[0063] The difference between embodiment 3 and embodiment 1 lies in that in this embodiment, lateral alternating water flow is selected for lateral oscillation. The immunomagnetic beads shake slightly under the force of the lateral alternating water flow, and the speed and pass rate of the immunomagnetic beads passing through the cell sieve are very high.
