Used in targeted cancer therapies, particularly in diagnosing and treating gastrointestinal stromal tumors (GISTs) and other malignancies expressing c-Kit. Binds specifically to the c-Kit receptor, enabling detection in immunohistochemistry and flow cytometry. Supports research and development of monoclonal antibody-based treatments by blocking receptor activation involved in cell proliferation and survival. Also utilized in isolating c-Kit-positive cells for stem cell and hematopoiesis studies.
