Background technology
Immunostaining is the principle utilizing antigen and antibody specific binding, detect the expression of specific protein (antigen), be find one of body method that changes of function is the most frequently used under physiology or pathological state, the most frequently used is immunohistochemical staining and immunofluorescence dyeing.In experimentation, often need research at least two kinds of antigen/protein expression in same cell or tissue sample, so that their respective location clear and definite or coexpression situation.The method the most often adopted at present adopts flow cytometry, but the cell concentration that this technology needs is larger, and be used for Flow cytometry poor effect through fixing and paraffin-embedded tissue, accurately can not show various antigen at tissue and cell natural distribution and status in vivo.If tissue specimen amount few (as cytological samples obtained by fine-needle aspiration) or the interior cell concentration to be detected of tissue are seldom, be then difficult to carry out Flow cytometry.By carrying out repeatedly immunostaining to same sample on tissue sections, the expression of research plurality of antigens, then can address this problem.Such as, after histotomy being carried out to the immunofluorescence dyeing of antigen A, Non-covalent binding is combined into due to antigen and antibody, and it is insecure, tissue can be put into damping fluid, suitably heat, just can make to separate to the antibody that antigen A combines and corresponding developer, can carry out again the immunofluorescence dyeing of antigen B, adopting uses the same method can also carry out the dyeing of antigens c, antigen D.There is the Multiple immunizations staining technique for histotomy at present, namely same histotomy is once dyeed, research plurality of antigens is expressed, as a kind of based on the Double-immunofluorescent labeling method (CN201410099873.2) of same Species origin first antibody, the shortcoming of this method is, in specific implementation process, the antigen carrying out marking is needed to be not only often two kinds, it is in most cases 5-10 kind, even reach more than 20 to plant, this multiple staining method can not be satisfied the demand, and needs repeatedly to dye.Certainly, multiple staining can be combined with repeatedly colouring method, can increase work efficiency.An important problem is, even the immunostaining of single, it has been recurrent problem that histotomy departs from microslide, repeatedly dyes and more easily causes histotomy to depart from microslide, cause experiment to carry out.A kind of anticreep slide device (CN201220446225.6) departs from the measure of microslide although provide a kind of feasible histotomy that prevents, and is not suitable for the dyeing of multi-time no epidemic disease.Thus, provide a kind of device that histotomy can be made to stand repeatedly immunostaining very necessary.
In addition, in repeatedly dyeing course, take pictures after needing to dye to tissue, compared by stained photographs repeatedly, just can understand which albumen same cell expresses actually, thus, the device provided also will be convenient to take pictures under the microscope at every turn.
Summary of the invention
Technical problem to be solved in the utility model be for existing microslide in the problem easily departing from microslide for histotomy during repeatedly immunostaining, a kind of slide glass folder for carrying out repeatedly (5 ~ 20 times) immunostaining to histotomy is provided.
The technical scheme in the invention for solving the above technical problem is: a kind of for histotomy is carried out repeatedly to immunostaining slide glass folder, comprise continue mutually upper slice and bottom sheet two parts composition.As preferred scheme, described upper slice be made up of the webbing upwards swelled and inner sieve-like cover plate, sieve-like coverslip thickness is 0.13mm ~ 0.16mm, there is fine and closely woven hole, aperture can ensure to allow macro-molecular protein (as mouse IgG) freely pass through and normal cell not by, optimum aperture is 3 μm ~ 5 μm, and pitch of holes is equal with aperture, and the thickness of webbing is best with 1mm ~ 2mm; As the scheme of secondary choosing, the part of described upper slice inside sieve-like cover plate can not have hole, structure is identical with following bottom sheet, but the shortcoming of this scheme is dyeing liquor only can arrive histotomy from the gap of surrounding by diffusion, can bring the long and uneven problem that dyes of dyeing required time.Described bottom sheet is made up of the webbing swelled downwards and inner slide glass, slide glass is similar to the cover glass that commercially available histopathological examination uses, good light transmission can be ensured, be adapted at basis of microscopic observation and take pictures, the suitableeest thickness is 0.13mm ~ 0.16mm, atresia, the thickness of webbing is best with 1mm ~ 2mm.Upper slice and bottom sheet opposite face smooth, size and shape is consistent, can be rectangle or square and other shapes, is good, can be made into plurality of specifications, as 24mm × 32mm, 18mm × 18mm with reference to the size of existing commercially available cover glass with square and rectangle.Upper slice with have a limit to continue mutually in the corresponding limit of bottom sheet, slide glass is made to press from both sides the shape being similar to book, when fully open upper slice time, histotomy can be positioned in bottom sheet smoothly, when upper slice downwards and bottom sheet is tightly drawn close time, upper slice and bottom sheet between form the gap that a width is 4 μm ~ 6 μm, histotomy to be clipped in wherein and can not displacement.Described slide glass folder adopts duroplasts to make, the hardness of these plastic products between 100R ~ 135R, water white transparency, acid and alkali-resistance and organic solvent, the high temperature of resistance to 100 DEG C.This slide glass folder, except for except immunostaining, also can be used in situ hybridization and the detection of relevant biomedicine thereof.
It is simple that the utility model provides a kind of structure, with low cost, can ensure the stability of histotomy and antibody and contact tissue response availability preferably, be convenient to take pictures.
