Gewebemarkierung

Gewebemarkierung, also known as tissue marking, is a technique used in medical and scientific fields to identify and label specific areas of tissue for further analysis or surgical procedures. This process involves the application of a marker to the tissue, which can be visible or invisible, depending on the type of marker used. The most common visible markers include ink, dyes, and fluorescent substances, while invisible markers often involve the use of radioactive isotopes or antibodies.

The choice of marker depends on the specific requirements of the study or procedure. For example, in surgical planning, visible markers such as surgical clips or dyes are commonly used to highlight areas of interest. In research, fluorescent markers are often preferred for their ability to be visualized under a microscope, allowing for detailed analysis of cellular structures.

Invisible markers, such as radioactive isotopes, are used when the tissue needs to be analyzed using techniques like autoradiography or scintigraphy. Antibodies, which are proteins used to identify specific molecules, are also commonly used as invisible markers in immunohistochemistry, a technique used to study the expression of proteins in cells.

Gewebemarkierung is a crucial tool in various fields, including pathology, oncology, and neuroscience, as it allows researchers and clinicians to precisely target and study specific areas of tissue. The technique has evolved significantly over the years, with advancements in marker technology improving the accuracy and efficiency of tissue marking.
