Description

Technical Field

[0001] This utility model relates to a biomedical research and development device, and more specifically, to a magnetic porous reaction plate. Background Technology

[0002] Magnetic bead technology has wide applications in the life sciences (biology, basic medicine, pharmacy, etc.), especially in the separation, enrichment, purification and detection of biomolecules.

[0003] Magnetic bead technology can be used to separate and enrich biomolecules such as DNA (deoxyribonucleic acid), RNA (ribonucleic acid), proteins, and cells. By combining specific targets with surface-functionalized magnetic beads, the target molecules can be selectively enriched, while the target molecules can be easily separated and recovered by applying an external magnetic field.

[0004] Magnetic bead technology can be used for efficient purification of DNA and RNA: specific ligands or affinity modifiers on the surface of magnetic beads can specifically bind to target DNA / RNA fragments, and non-specific bindings can be removed by a washing step, thereby achieving high-purity DNA / RNA purification.

[0005] Magnetic bead technology can be used for antibody purification and separation: by binding antigens to magnetic beads, specific antibodies can be selectively enriched and purified. Furthermore, magnetic bead technology can also be used in immunoassays, such as ELISA and immunomagnetization assays.

[0006] Magnetic bead technology can be used for the rapid separation and enrichment of cells: antibodies or other affinity molecules on the surface of magnetic beads can bind to specific antigens on the cell surface, thereby achieving selective enrichment of specific cell subpopulations. Furthermore, magnetic bead technology can also be used for cell labeling and tracking; by labeling magnetic beads with specific functions or properties, cell localization and monitoring can be achieved.

[0007] In high-throughput experiments, magnetic bead technology often uses a porous reaction plate in conjunction with a magnetic frame to separate the magnetic beads. Once the porous plate is removed from the magnetic frame, the magnetic force on the beads within the pores disappears. Summary of the Invention

[0008] This invention provides a magnetic porous reaction plate for life science experimental research using magnetic beads, which enables the movement, centrifugation, and shaking of the porous reaction plate while maintaining magnetic force.

[0009] The technical solution of this utility model is as follows:

[0010] A magnetic porous reaction plate includes a porous plate 1, a base 2, a cover plate 3, and a magnet 4. The porous plate 1 can be fitted into the base 2, and the cover plate 3 can be tightly covered on the base 2.

[0011] The magnet 4 can be embedded between the multi-well plate 1 and the base 2 and fits the shape of the bottom of the multi-well plate.

[0012] The cover plate 3 has a sealing gasket 5 inside.

[0013] The multi-well plate 1, the base 2, and the cover plate 3 are made of a strong, corrosion-resistant, and transparent plastic, such as polystyrene or polypropylene.

[0014] The magnet 4 is made of a neodymium iron boron (NdFeB) magnet.

[0015] The sealing gasket 5 is made of rubber, silicone, or plastic.

[0016] One use method of the present application is to sequentially add a reaction solution into the multi-well plate 1, embed the magnet 4 in the base 2, then embed the multi-well plate 1 containing the solution on the magnet 4 in the base 2, cover the cover plate 3, as shown in Figure 2 , and perform moving, centrifuging, shaking, and other experimental operations.

[0017] The present application can also be used without a magnet: sequentially add a reaction solution into the multi-well plate 1, then embed the multi-well plate 1 containing the solution in the base 2, cover the cover plate 3, as shown in Figure 3 , and perform moving, centrifuging, shaking, and other experimental operations.

[0018] The present application has the beneficial effect of enabling moving, centrifuging, shaking, and other operations on the multi-well reaction plate while maintaining the magnetic force, thereby enabling more flexible and diverse experimental design and experimental schemes.
