  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. 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.

  5. SOX10 - Wikipedia

    en.wikipedia.org/wiki/SOX10

    SOX10 immunohistochemistry facilitates showing lentigo maligna, as an increased number of melanocytes along stratum basale and nuclear pleumorphism. The changes are continuous with the resection margin (inked in yellow, at left), conferring a diagnosis of a not radically removed lentigo maligna.

  6. Staining - Wikipedia

    en.wikipedia.org/wiki/Staining

    Unlike negative staining, positive staining uses basic dyes to color the specimen against a bright background. While chromophore is used for both negative and positive staining alike, the type of chromophore used in this technique is a positively charged ion instead of a negative one. The negatively charged cell wall of many microorganisms ...

  7. Immunohistochemistry test - Wikipedia

    en.wikipedia.org/wiki/Immunohistochemistry_test

    The immunohistochemistry (IHC) test is a laboratory method that detects antibodies of prions (mis-shapen proteins thought to transmit bovine spongiform encephalopathy, BSE or mad cow disease) by exposing a brain sample to a stain that appears as a specific color under a microscope.

  8. 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 ...

  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]
