描述（Description）
The Human c-MET (Luc) HEK293 Reporter Cell was engineered to express signaling response element driving luciferase expressing systems and human c-MET (Gene ID: 4233). When stimulated with human HGF protein, the HGF/c-MET interaction drives RE-mediated luminescence. Neutralization of biological effect of human HGF protein by corresponding antibody results in a decrease in luminescence.
应用说明（Application）
• Screen for neutralizing antibodies blocking the stimulation of human HGF protein.

Receptor Assay
Expression analysis of human c-MET on Human c-MET (Luc) HEK293 Reporter Cell by FACS.
Cell surface staining was performed on Human c-MET (Luc) HEK293 Reporter Cell or negative control cell using PE-labeled anti-human c-MET antibody.
Protocol
Application
Inhibition of human HGF protein-induced reporter activity by anti-human c-MET neutralizing antibody.
This reporter cell was incubated with serial dilutions of antibodies in the presence of human HGF protein with a final concentration of 0.05 μg/mL. The EC50 of anti-human c-MET neutralizing antibody (Amivantamab) is approximately 0.06561 μg/mL.
Protocol
Signaling Bioassay
Response to human HGF protein (RLU).
This reporter cell was incubated with serial dilutions of human HGF protein. The EC50 was approximately 0.03652 μg/mL.
Protocol
Response to human HGF protein (FOLD).
This reporter cell was incubated with serial dilutions of human HGF protein. The max induction fold was approximately 38.12.

背景（Background）
Hepatocyte growth factor receptor (HGFR) is also known as mesenchymal-epithelial transition factor (MET), c-Met, and is a glycosylated receptor tyrosine kinase that plays a central role in epithelial morphogenesis and cancer development. HGFR protein possesses tyrosine-kinase activity. The primary single chain precursor protein is post-translationally cleaved to produce the alpha and beta subunits, which are disulfide linked to form the mature receptor. HGFR is normally expressed by cells of epithelial origin, while expression of HGF is restricted to cells of mesenchymal origin. Upon HGF stimulation, HGFR induces several biological responses that collectively give rise to a program known as invasive growth. Abnormal HGFR activation in cancer correlates with poor prognosis, where aberrantly active HGFR triggers tumor growth, formation of new blood vessels (angiogenesis) that supply the tumor with nutrients, and cancer spread to other organs (metastasis). HGFR is deregulated in many types of human malignancies, including cancers of kidney, liver, stomach, breast, and brain. Normally, only stem cells and progenitor cells express HGFR, However, cancer stem cells are thought to hijack the ability of normal stem cells to express HGFR, and thus become the cause of cancer persistence and spread to other sites in the body. Various mutations in the HGFR gene are associated with papillary renal carcinoma. HGFR mediates a complex program known as invasive growth. Activation of HGFR triggers mitogenesis, and morphogenesis.
