Used in research to study receptor tyrosine kinase signaling pathways involved in cell development and cancer progression. Binds specifically in assays to detect protein interactions and is utilized in immunoassays due to the Fc tag, which allows for easy detection and purification. Supports development of targeted therapies by helping identify ligands and downstream effectors in developmental biology and oncology studies. Commonly used in ELISA, flow cytometry, and protein-protein interaction experiments.
