CD68

CD68 is a protein found mainly in certain immune cells called macrophages, which help the body fight infections and clear damaged cells. Scientists use CD68 as a marker to identify and study these macrophages in tissue samples. By observing CD68, researchers can assess immune activity within tissues, such as in inflammation or tumors, providing insights into disease processes. It is a useful tool in medical research and diagnostics to understand how the immune system interacts with various conditions.
