Used in targeted cancer therapy, particularly for tumors expressing c-Met receptor. Blocks hepatocyte growth factor (HGF) signaling pathway, inhibiting tumor growth, angiogenesis, and metastasis. Investigated in clinical trials for non-small cell lung cancer and other solid tumors. Employed as a reference in immunoassays and antibody development due to its high specificity and neutralizing activity. Supports research in oncology and drug discovery by serving as a benchmark for anti-HGF/SF antibody performance.
