Used in targeted cancer therapies, particularly for tumors expressing c-Kit, such as gastrointestinal stromal tumors (GIST) and certain types of leukemia. This antibody binds selectively to the c-Kit receptor, blocking its activation and downstream signaling pathways involved in cell proliferation and survival. It is also employed in diagnostic applications to detect c-Kit expression in tissue samples, aiding in disease classification and treatment planning. Additionally, it serves as a reference standard in the development of biosimilars and immunoassays.
