In order to perform immunohistochemistry, it is necessary to have access to a laboratory along with a number of specialized products which will be used to prepare and test the sample. When someone does an immunohistochemistry study, he or she introduces specialized antibodies to a sample of the ...
Immunohistochemistry (IHC) is a special test used bypathologiststo detect specific molecules on cells. Christopher Furlong / Getty Images When a tissue sample such as a lymph node biopsy is passed to a lab to be examined for disease, there are several details that cannot be determined easily. ...

Doctors can confirm whether you have HR+ or HR− cancer through an immunohistochemistry test. For this test, a biopsy is done to collect a sample of tumor tissue and send it to a lab for examination. A similar test can be done to determine whether breast cancer is HER2+ or HER2−...
How Is It Diagnosed? If you or someone in your family gets cancer, the doctor can do one of these tests on a small sample of the tumor to look for signs of Lynch syndrome: Immunohistochemistry(IHC) tests use dye to mark proteins in the tumor sample. If certain proteins aren't there,...

ImmunohistochemistryPrognosisResponseOver-expression of the epidermal growth factor receptor (EGFR) in tumours is associated with aggressive disease and poor clinical prognosis. In theory, the EGFR status of a tumour provides an indication of the likelihood of response to EGFR-targeted therapy. However,...
(e.g., IgM or IgG), and the kind of label which is preferred. The optimal secondary antibody is normally identified through trial and error. Secondary antibodies have been very useful for many biochemical assays, including immunocytochemistry, ELISA, western blot, immunohistochemistry, and so on....

Although it is difficult to overcome the inherent obstacles of contemporary immunohistochemistry, other bio- logical platforms may offer a more robust alternative. As an example, several mRNA expression signatures have been proposed to predict disease progression and are currently undergoing intense ...
