Flow Cytometry and Immunohistochemistry (IHC)
Flow cytometry and immunohistochemistry (IHC) are powerful techniques used in surgical oncology to analyze and differentiate between different cell types within a tissue sample. These techniques employ different methods to identify and sort cells based on specific characteristics, allowing for the identification and characterization of cancerous cells.
Flow Cytometry
Flow cytometry is a technique used to analyze the physical and chemical characteristics of single cells. Cells are stained with fluorescent dyes that bind to specific molecules or antigens, which are then detected using a flow cytometry analyzer. The analyzer sorts the cells based on the intensity and location of these dyes, providing information about the cell's phenotype.
Immunohistochemistry
Immunohistochemistry is a technique used to visualize and identify specific proteins or markers in tissue sections. Antibodies, which are specific proteins, are used to label cells that express the target protein. The sections are then stained with a chromogenic or fluorescent substrate, which binds to the antibodies and produces a colored signal.
The combination of flow cytometry and IHC allows for the identification and characterization of cells based on both their phenotypic and molecular characteristics. This technique is widely used in surgical oncology for the diagnosis, staging, and prognosis of cancer patients
