Used to measure the activity of Receptor Tyrosine Kinases (RTKs) in human samples, this ELISA kit is essential in cancer research and drug development. It enables researchers to monitor RTK phosphorylation, a key step in cell signaling pathways linked to tumor growth and metastasis. The kit supports high-throughput screening of kinase inhibitors, helping evaluate potential therapeutic compounds. It is widely used in biomedical labs to study diseases involving abnormal RTK activation, such as leukemia, lung cancer, and diabetes. The assay provides quantitative results with high sensitivity and specificity, making it ideal for both basic research and clinical investigation.
