Immunocytochemistry

Immunocytochemistry is a laboratory technique used to identify specific proteins in cells using antibodies. Antibodies are special proteins that can bind to target proteins, marking them for detection. In this method, cells are treated with these antibodies, which are often linked to a color-producing enzyme or fluorescent dye. When observed under a microscope, the areas where the antibodies bind to their target proteins can be visualized, revealing information about the protein's presence and location. This technique is widely used in research and medical diagnostics to study diseases, including cancer.
