Description
Technical field
The invention belongs to medical treatment to detect instrument field, particularly relate to be related to immunohistochemistry and immunocytochemical stain
Technical field more specifically refers to a kind of improved structure for the device of biological sample dyeing module on glass slide.
Background technology
Immunohistochemistry technology (Immunohistochemis try, IHC) is to combine to exempt from histochemical method
The new technology that the theory and technology of epidemiology grows up, combines the reason of the subjects such as immunology, histology and biochemistry
By and method.Using immunologic core, i.e., the principle that antigen and antibody specificity combine, with enzyme, metal ion, same is marked
The antibody such as position element track antigen, are shown with the developer on the specific antibody on antigen by chemically reacting to make to be marked on to combine
Certain color, and the result of dyeing is observed by microscope, fluorescence microscope, Electronic Speculum, to reach detection antigen
The purpose of object.
Immunohistochemistry has a long history, and the phase that immunofluorescence technique detects frozen section is established from Coons in 1940
Antigen is answered, has 73 history so far.Nineteen sixty-five, Liu Yanfang etc. establish immunohistochemistry technology at home for the first time, however
Until in the early 1990s, appearance this method of antigen retrieval is just widely used in pathological diagnosis.The technology undergoes 4 development
Stage：The foundation of immunohistochemistry technique and developing stage；Popularize the stage；Clinicopathologic Diagnosis and application stage；Quality control
System, standardization and normalization period.Now, without immunohistochemical auxiliary, many tumours can hardly be made accurately
Diagnosis and classification.Meanwhile extensive use of the immunohistochemistry in Clinicopathologic Diagnosis has also pushed immunohistochemistry technique itself
Fast development.
So far from nineteen fifty, Journal of Histochemistry＆Cytochemistry published largely with tissue
The document of the relevant new technology of Morphologic Diagnosis, such as enzyme labeled immunoassay group, Avidin biotin detection system, cascin signal
Amplification system etc..All these valuable discoveries promote clinical and basic biomedical research in worldwide
Development.Immunohistochemistry has been widely applied and has been approved, link indispensable in pathological diagnosis is had become.Immune group
Change the accuracy for not only increasing pathological diagnosis, while having penetrated into basis and clinical speciality, in the teiology for inquiring into disease, sends out
Play the role of in interpretation of the cause, onset and process of an illness system and research work immeasurable.
Key step during immunohistochemical staining includes：Roasting piece, dewaxing, aquation, antigen retrieval or peroxidase
Block (can selectively add), primary antibody, secondary antibody or three anti-(alternative additions), DAB or haematoxylin (alternative addition)
And all flushings.
With the development of science and technology, various advanced technologies are also gradually applied in the automation dyeing course of immunohistochemistry, with
Substitute hand dyeing.
In each step of immunohistochemical staining, the most it is difficult to antigen retrieval process, because tissue fixation is the most frequently used
Fixative be formaldehyde, formaldehyde can be crosslinked with protein in organize fixation procedure reacts, and forms a kind of friendship of methylene bridge
It is coupled structure, to make antigenic determinant in tissue be shielded.Professor Shi Shanrong has found, caused by heating can destroy formaldehyde fixation
Protein-crosslinking makes shielded antigenic determinant be exposed again, so as to be combined with corresponding antibodies.
Currently, the selection of antigen retrieval mode and reagent type is more flexible during manual immunohistochemical staining, commonly use
Heat guiding antigen retrieval mode have：High pressure, boiling, microwave, water-bath etc.；Common antigen retrieval buffers have citric acid (pH6.0),
EDTA(pH9.0)、Tris-HCL(pH9.0-10).And different laboratories because testing staff, heater element selection, plus
There may be differences for each link such as the control of hot temperature and time, so that in immunohistochemical staining result inevitably
It can have differences.
In order to overcome the difference of artificially colored result, immunohistochemistry automation coloring system to be developed, also, close
The automatic clinical chemistry analyzer of Nian Lai, various different models and function emerges in large numbers in succession, greatly improves working efficiency and inspection
Accuracy.But full-automatic dyeing instrument currently on the market is to heat temperature using to antigen retrieval buffers for antigen retrieval
Degree is less than 100 DEG C, although it is expected to realize high temperature reparation by adding high boiling substance in antigen retrieval buffers now with producer,
But during antigen retrieval, after the heating, need to be rinsed again after glass slide cools down, in order to improve cooling rate,
It is cooling velocity to be improved by fan, but while fan coolling, the surface of the histotomy on glass slide can be caused
There is dry-out phenomenon, and influences the effect combined with corresponding antibodies.
