Description

Technical Field

[0001] The utility model relates to the technical field of cell culture, in particular to a cell culture dish and an experimental method convenient for Transwell experiment. Background Art

[0002] The Transwell assay is an experimental technique that can assess both cell migration and invasion abilities. The main material of this technique is a Transwell chamber with a microporous membrane. The Transwell chamber studies cell motility by simulating the behavior of cells crossing the basement membrane and is widely used in fields such as oncology, immunology, and cell biology.

[0003] The existing Transwell chamber system consists of multiple Transwell chambers placed in a multi-well plate. Cell culture procedures are performed on each chamber in the well. The chamber, shaped like a small cup that fits within the plate, is crucially designed to contain a permeable membrane at the bottom. The basic principle of a Transwell experiment involves placing a Transwell chamber in a culture plate. The upper chamber holds the upper culture medium and cells, while the lower chamber holds the lower culture medium. The upper and lower layers are separated by a microporous membrane.

[0004] In current Transwell chambers, cells penetrate the upper chamber and remain in the lower chamber. Because of the porous membrane, cells trapped in the lower chamber after passing through the upper chamber cannot be directly observed after staining. The porous membrane often needs to be cut and mounted for observation. Because the porous membrane is small and very thin, it is not only inconvenient to handle, but also easily damaged during cutting or mounting, which can affect experimental results.

[0005] In order to solve the above technical problems, the utility model provides a cell culture dish that is convenient for Transwell experiment, simplifies the operation process of traditional Transwell experiment, eliminates the need to cut and slice the porous membrane, effectively reduces the possibility of damage to the porous membrane, and improves the success rate of the experiment.

[0006] In order to achieve the above-mentioned object, the utility model provides a cell culture dish that is convenient for Transwell experiment, comprising a culture vessel, a glass slide, and a vertical slot plate, wherein the vertical slot plate is fixed to the inner wall of the culture vessel, and a slot for inserting the glass slide is provided at the top of the vertical slot plate;

[0007] The glass slide is provided with a perforation, a porous membrane is fixed to one side wall of the glass slide, and the porous membrane covers the perforation; the glass slide is connected to the culture vessel through a vertical slot plate, and the inner cavity of the culture vessel is divided into two culture cavities.

[0008] Furthermore, the vertical slot plate is a U-shaped plate body consisting of a bottom plate and two side plates integrally formed at both ends of the bottom plate.

[0009] Furthermore, the vertical slot plate is made of silicone rubber.

[0010] Furthermore, the porous membrane is a polycarbonate membrane or a polyester membrane.

[0011] Furthermore, a horizontal support is provided in the culture vessel, and the slide can be placed horizontally on the horizontal support, and the height of the horizontal support is greater than the height of the bottom plate of the vertical slot plate.

[0012] Beneficial effects of the utility model:

[0013] The utility model designs a novel glass slide structure to cooperate with a culture vessel, adheres a porous membrane to the surface of the glass slide, and inoculates cells on the porous membrane of the glass slide, which is then fixed vertically in the culture vessel, and the culture vessel is divided into two culture chambers. Induction factors are added to the culture medium of one of the culture chambers to induce cell invasion and metastasis, so that the glass slide can be directly removed for staining and observation, simplifying the operation process of the traditional Transwell experiment, eliminating the need to cut the porous membrane to make slices, effectively reducing the possibility of damage to the porous membrane, and improving the success rate of the experiment.
