Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and specifically relates to a brain slice transfer rod. Background Art

[0002] Brain slice experiments use staining technology to mark specific proteins on brain slices in order to accurately detect their expression levels or expression areas, thereby supporting neuroscience research and disease diagnosis. During the process, the cut brain slices need to be placed one by one in the wells containing blocking fluid, and after shaking on a shaker, they need to be transferred for subsequent operations.

[0003] In the process of transferring brain slices, a writing brush is usually used as the main tool, which has some significant disadvantages; the structure of the writing brush is composed of many fine hairs, which easily form gaps between the hairs when immersed in liquid, causing the brain slice to be clamped by the writing brush during transfer, which not only increases the risk of brain slice damage, but also makes it difficult for the brain slice to fall off smoothly into the rinsing solution; the writing brush will inevitably carry some liquid when transferring brain slices. When transferring from the rinsing solution to a smaller volume of dye solution, these residual liquids may cause the dye solution to be diluted, thereby affecting the dyeing effect.

[0004] Using a brush as a brain slice transfer tool has low experimental efficiency and increases the complexity and potential error rate of the operation.

[0005] In view of the above problems, the utility model provides a brain slice transfer rod. Utility Model Content

[0006] In order to overcome the problems raised in the background technology, the design of the brain slice transfer rod is improved, which can effectively avoid the dilution of the dye solution and affect the dyeing effect, improve the consistency and accuracy of the dyeing, and also improve the work efficiency of the experimenters. The utility model adopts the following technical solutions:

[0007] A brain slice transfer rod comprises a handheld handle and an operating rod; the handheld handle has a first end and a second end, the first end of the handheld handle is fixedly connected to the operating rod, the end of the operating rod away from the handheld handle is provided with a bending section, the bending section is fixedly connected to the operating rod, and the angle between the bending section and the operating rod is an obtuse angle; the bending section can lift the brain slice, so that the experimenter can transfer the brain slice to the rinsing solution more quickly, which significantly improves the work efficiency, accurately controls and optimizes the contact area of ​​the brain slice, greatly reduces the mechanical damage to the brain slice, and reduces the influence of the brain slice on the liquid concentration when transferring between different liquids, especially when transferring the brain slice from the rinsing solution to the dye solution, effectively avoiding the liquid cross contamination and dilution problems.

[0008] Furthermore, the angle between the bending section and the operating rod is 120 degrees. This specific angle layout makes it more convenient and efficient for experimenters to operate the brain slice selection and transfer process.

[0009] Furthermore, a round head is provided at the end of the bending section away from the operating rod, which can ensure that no damage is caused to the brain slice when the brain slice is supported and transferred.

[0010] Furthermore, the outer surfaces of the operating rod and the bending section are set to be smooth and made of hard material.

[0011] Furthermore, the shape of the hand-held handle is cylindrical, and the diameter of the first end of the hand-held handle gradually decreases. The above arrangement is conducive to observation by experimenters and prevents the first end of the hand-held handle from being too thick and blocking the line of sight.

[0012] Furthermore, the axial direction of the operating rod is perpendicular to the end surface of the first end of the hand-held handle.

[0013] Furthermore, the hand-held handle is provided with anti-slip grooves, which ensures a stable grip when used by an experimenter and prevents slipping during use.

[0014] Furthermore, the diameter of the hand-held handle is 6 mm. The above configuration provides a stable and comfortable grip for the experimenter, thereby enhancing control accuracy and reducing fatigue.

[0015] Furthermore, the diameter of the operating rod and the bending section is 1 mm, which can avoid dilution of the liquid while ensuring that the brain slice will not be damaged due to being too sharp.

[0016] The beneficial effects of the utility model are as follows: the utility model has a reasonable structure; by providing an operating rod and a bending section, the bending section can lift the brain slice, and the experimenter can transfer the brain slice to the rinsing solution more quickly, which significantly improves work efficiency, accurately controls and optimizes the contact area of ​​the brain slice, greatly reduces mechanical damage to the brain slice, and reduces the influence of the brain slice on the liquid concentration when transferring between different liquids, especially when transferring the brain slice from the rinsing solution to the dye solution, effectively avoids liquid cross-contamination and dilution problems; by providing anti-slip patterns on the handheld handle, it ensures that the experimenter has a stable grip when using it, prevents sliding during use, and can significantly improve the accuracy of experimental operations and the user experience.

[0027] The connection between the bending section 3 and the operating rod 2 is smoothly connected.

[0028] Please refer to Figure 3 In this embodiment, the angle between the bending section 3 and the operating rod 2 is 100-150 degrees, preferably 120 degrees. This specific angle layout makes it more convenient and efficient for experimenters to operate brain slice selection and transfer.

[0029] Please refer to Figure 3 In this embodiment, a round head 4 is provided at the end of the bending section 3 away from the operating rod 2 to ensure that no damage is caused to the brain slice when the brain slice is supported and transferred.

[0030] The outer surfaces of the operating rod 2 and the bending section 3 are set to be smooth and made of hard material. Preferably, the material is alloy.

[0031] Please refer to Figure 2 The shape of the hand-held handle 1 is cylindrical, and the diameter at the first end of the hand-held handle 1 gradually decreases.

[0038] 1. First, add the blocking solution to the 24-well cell culture dish, adding 400-500 μL to each well. The blocking solution is used to prevent non-specific binding and ensure the specificity of staining.

[0039] 2. Use a brain slice transfer rod to place the slices into the wells containing the blocking solution one by one, 3-4 slices per well. Shake at 50 rpm for 1.5-2 hours on a shaker in a dark environment to promote the effect of the blocking solution.

[0040] 3. Dispense the primary antibody solution into a new 24-well cell culture dish, adding 400-500 μL to each well.

[0041] 4. Use a brain slice transfer rod to transfer the brain slices from the blocking solution to the wells containing the primary antibody solution. Place the culture dish on a shaker at 4°C away from light, set the speed to 50 rpm, and incubate overnight to allow the antibody to bind to the target protein.

[0042] 5. Place the rinse solution in a 6-well cell culture dish, about 5 ml per well, to wash the brain slices to remove unbound primary antibody.

[0043] 6. Use a brain slice transfer rod to transfer the brain slices to the wells containing the rinse solution and wash them on a light-proof shaker at 120 rpm for 5 minutes to remove unbound primary antibodies.

[0044] 7. Repeat step 6 twice to ensure thorough cleaning.

[0045] 8. Add the secondary antibody solution to a new 24-well cell culture dish, 400-500 μL per well.

[0046] 9. Use a brain slice transfer rod to transfer the brain slices to the wells containing the secondary antibody solution and place them on a shaker at 50 rpm for incubation for 2-4 hours away from light.

[0047] 10. Use the brain slice transfer rod again to transfer the brain slice to a 6-well cell culture dish containing the rinse solution, and wash it at 120 rpm for 5 minutes on a light-proof shaker.

[0048] 11. Repeat step 10 twice to ensure thorough cleaning.
