  2. Immunohistochemistry - Wikipedia

    en.wikipedia.org/wiki/Immunohistochemistry

    Immunohistochemistry can be performed on tissue that has been fixed and embedded in paraffin, but also cryopreservated (frozen) tissue.Based on the way the tissue is preserved, there are different steps to prepare the tissue for immunohistochemistry, but the general method includes proper fixation, antigen retrieval incubation with primary antibody, then incubation with secondary antibody.

  3. Immunostaining - Wikipedia

    en.wikipedia.org/wiki/Immunostaining

    Immunohistochemistry or IHC staining of tissue sections (or immunocytochemistry, which is the staining of cells), is perhaps the most commonly applied immunostaining technique. [2] While the first cases of IHC staining used fluorescent dyes (see immunofluorescence ), other non-fluorescent methods using enzymes such as peroxidase (see ...

  4. Immunofluorescence - Wikipedia

    en.wikipedia.org/wiki/Immunofluorescence

    Immunofluorescence is a widely used example of immunostaining (using antibodies to stain proteins) and is a specific example of immunohistochemistry (the use of the antibody-antigen relationship in tissues). This technique primarily utilizes fluorophores to visualize the location of the antibodies, while others provoke a color change in the ...

  5. Cytokeratin 5/6 antibodies - Wikipedia

    en.wikipedia.org/wiki/Cytokeratin_5/6_antibodies

    Immunohistochemistry with cytokeratin 5/6 antibodies in usual ductal hyperplasia, showing a mosaic pattern, predominantly in the central zone. Cytokeratin 5/6 antibodies are antibodies that target both cytokeratin 5 and cytokeratin 6. [1] These are used in immunohistochemistry, often called CK 5/6 staining, [2] including the following applications:

  6. Immunoperoxidase - Wikipedia

    en.wikipedia.org/wiki/Immunoperoxidase

    Immunoperoxidase is a type of immunostain used in molecular biology, medical research, and clinical diagnostics.In particular, immunoperoxidase reactions refer to a sub-class of immunohistochemical or immunocytochemical procedures in which the antibodies are visualized via a peroxidase-catalyzed reaction.

  7. Immunocytochemistry - Wikipedia

    en.wikipedia.org/wiki/Immunocytochemistry

    In contrast, immunohistochemical samples are sections of biological tissue, where each cell is surrounded by tissue architecture and other cells normally found in the intact tissue. Immunocytochemistry is a technique used to assess the presence of a specific protein or antigen in cells (cultured cells, cell suspensions) by use of a specific ...

  8. Staining - Wikipedia

    en.wikipedia.org/wiki/Staining

    The negatively charged cell wall of many microorganisms attracts the positively charged chromophore which causes the specimen to absorb the stain giving it the color of the stain being used. Positive staining is more commonly used than negative staining in microbiology. The different types of positive staining are listed below. [1]

  9. Antigen retrieval - Wikipedia

    en.wikipedia.org/wiki/Antigen_retrieval

    Antigen retrieval techniques (AR) has had a profound impact on medical research and diagnostic pathology, enabling more accurate and reliable staining of tissue samples and improving the diagnostic accuracy of various diseases, including cancer. Antigen retrieval is considered as a milestone in the history of immunohistochemistry. [3]
