MMR panel | MSH2 (C2G3), MMab
MSH2 is an important gene in the human mismatch repair gene family. Human mismatch repair genes play an important role in maintaining the integrity and stability of genetic information and avoiding the production of genetic mutations. At present,MSH2 is used in the study of hereditary non- polypsy colorectal cancer with MLH1, MSH6, PMS2 together.

Product Features
[Intended Use]
This antibody is intended for use in Immunohistochemical applications on formalin-fixed paraffin-embedded tissues (FFPE). The clinical interpretation of any staining or its absence should be complemented by morphological studies using proper controls and should be evaluated within the context of the patient’s clinical history and other diagnostic tests by a qualified pathologist.

[Protocol Recommendations]
This reagent has been optimized on the fully automatic immunohistochemical stainer and does not require reconstitution, mixing, dilution or titration.
For detailed operating parameters, please refer to the operating manual of the fully automatic immunohistochemical stainer.
1.Test Procedure:
1.1 Incubation with peroxidase block quenches the activity of endogenous peroxidase.
1.2 Use MSH6 to incubate.
1.3 Linker , rabbit-anti-mouse incubation.
1.4 Use polymer for incubation, and bind the reagent to linker , rabbit-anti-mouse .
1.5 Incubate the antigen-antibody complex with DAB, and finally appear in the form of a brown precipitate, which can be observed under a light microscope.
1.6 Use DAB Enhancer for incubation to enhance color intensity.
1.7 Incubate with hematoxylin and counterstain the sections.
1.8 Use bluing reagent to incubate and blue hematoxylin to enhance the contrast of the staining results.
2.Quality Control
2.1 Positive Control
Positive controls serve as an indication of correct tissue preparation and appropriate staining techniques. Each staining should include a positive pair of photos for comparison under the same test conditions. Known positive tissue controls should only be used to monitor the correct performance of procedures and testing of reagents and are not intended to aid in describing a definitive diagnosis of a patient sample. If the positive tissue control fails to show appropriate positive staining, the results of this batch of experimental test samples should be considered invalid.
2.2 Blank Control
Each staining should include a blank control reagent under the same test conditions for comparison. Blank control reagents are used to stain tissue sections instead of antibodies to judge non-specific staining and provide a better explanation for antigen site-specific staining.
