Moreover, the fluorescent colour signals exhibit a relatively consistent relationship to the actual antigen concentration in the test preparation and are hence better suited for quantitative computerized image analysis than light-microscopic observations of immunoenzyme staining. On the other hand, immuno...
Immunohistochemistry helps to detect cancer by staining specific proteins that are markers for cancerous tumors. Staining these proteins makes them easier to see and examine under a microscope. What is Immunohistochemistry? The definition ofimmunohistochemistryis a process in which antibodies and enzymes ...
For example, breast cells in a liver would indicate that the tumor was actually breast cancer which had metastasized to the liver. The antibodies can also be used to identify malignancy, which can help the pathologist determine the stage of the cancer. While immunohistochemistry is detailed, ...

Cells secrete a wide variety of proteins. Abnormal changes in a cell affect protein expression: some proteins cease expression, others overexpress, and some modify into a new protein. Classification of these changes is based on the area from which they originated. For each type of cancer within...
Combined application of RT-PCR and immunohistochemistry on paraffin embedded sentinel lymph nodes of prostate cancer patients The detection of tumor cells in the sentinel lymph node (SLN) is of great importance for the prognosis of cancer patients. At present, immunohistochemistry... CJ Haas,T Wagne...
