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.
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 ...
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 ...
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.
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:

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]
The use of tissue microarrays in combination with immunohistochemistry has been a preferred method to study and validate cancer biomarkers in various defined cancer patient cohorts. The possibility to assemble a large number of representative cancer samples from a defined patient cohort that also has a corresponding clinical database, provides ...
