Description

Slice staining rack for immunohistochemical experiment Technical Field The utility model relates to the technical field of equipment for immunological experiments, in particular to a slice staining rack for immunohistochemical experiments. Background Immunohistochemical experiments generally comprise a plurality of steps such as sample fixation, slicing, antigen retrieval, antibody incubation, color development and the like, specifically, biological cell tissues with a certain size are embedded in paraffin blocks, sliced by a slicing machine, stained, and the cell tissue structures are further observed by a microscope. When making sections, part of the cell tissue is treated by various chemicals and embedding methods to be fixed and hardened, and then cut into slices on a slicing machine, adhered to a glass slide, stained with various colors for observation under a microscope. The biological cell slice used at present is placed on a dyeing rack through a glass slide, the dyeing rack is square, the dyeing rack is placed in a square box containing dyeing liquid during dyeing, and dyeing is completed after lifting for several times. The square dyeing box is used in cooperation with the square dyeing rack, and due to limited space, the dyeing rack can only rise and fall in the vertical direction and cannot rotate in the horizontal direction, so that the dyeing effect is poor, clear observation under a microscope is not facilitated, and the experimental effect is affected. Therefore, it is necessary to develop a slice staining rack for immunohistochemical experiments, which can dye slices more sufficiently through rotating the staining rack, has a good staining effect, is convenient to observe under a microscope, and avoids experimental errors. Disclosure of utility model The utility model aims to provide the slice staining rack for immunohistochemical experiments, which can fully stain slices through rotating the staining rack, has good staining effect, is convenient to observe under a microscope and avoids experimental errors. The technical scheme is that the slice dyeing rack for the immunohistochemical experiment comprises a base, wherein a vertical shaft is vertically arranged in the middle of the base, a sleeve is sleeved outside the vertical shaft, an upper tray is arranged on the upper portion of the sleeve, a lower tray is arranged on the lower portion of the sleeve, the upper tray comprises an upper inner ring tray and an upper outer ring tray, the lower tray comprises a lower inner ring tray and a lower outer ring tray, the outer side of the upper inner ring tray and the inner side of the upper outer ring tray, and clamping grooves are correspondingly arranged on the outer side of the lower inner ring tray and the inner side of the lower outer ring tray in a radial mode around the center of the sleeve respectively, and glass slides with wax sealing slices are inserted in the clamping grooves. Further, the upper tray, the lower tray and the sleeve are connected through the vertical plates which are circumferentially arranged. Further, the shape of the base, the upper outer ring disc, the lower outer ring disc is set to one of a circular shape or a regular polygon. Further, the top of the vertical shaft is provided with threads, nuts are screwed on the threads, and gaps are formed between the top of the sleeve and the bottoms of the nuts, so that the sleeve can rotate around the vertical shaft. Further, a handle is arranged at the top of the vertical shaft. The device has the advantages that the glass slide with the cell slice is inserted into the clamping groove between the upper tray and the lower tray, the upper tray and the lower tray are connected with the sleeve through the vertical plate, the sleeve can rotate around the center of the vertical shaft, the dyeing rack is placed in the dyeing barrel during dyeing, the dyeing rack can be lifted up and down to make lifting and falling motions, and can rotate in the dyeing barrel, so that the slice dyeing is subjected to axial and radial immersion treatment, the dyeing is more uniform, the dyeing effect is good, the cell tissue structure can be observed more clearly under a microscope, experimental errors are avoided, and meanwhile, the device is in a detachable structure, convenient to clean after being detached, and convenient to store after being assembled. Drawings FIG. 1 is a schematic diagram of the overall structure of the present utility model; FIG. 2 is a cross-sectional view taken along line A-A of FIG. 1; In the figure, the glass slide is characterized by comprising a 1-base, a 2-lower tray, a 21-lower inner ring disc, a 22-lower outer ring disc, a 3-glass slide, a 4-upper tray, a 41-upper inner ring disc, a 42-upper outer ring disc, a 5-sleeve, a 6-vertical shaft, a 7-nut, an 8-handle, a 9-vertical plate and a 10-clamping groove.
