huVEGFR2-HEK293 is primarily used in biomedical research to study angiogenesis, the process of blood vessel formation. It serves as a critical tool for investigating signaling pathways involved in vascular development and tumor growth. Due to its role in mediating vascular endothelial growth factor (VEGF) responses, this protein is employed in assays to screen and evaluate potential anti-angiogenic drugs, especially in cancer therapy development. It is also utilized in cell-based assays to assess receptor activation, phosphorylation, and downstream signaling events. Its expression in HEK293 cells provides a stable and reproducible system for functional studies and antibody validation in immunological and oncological research.
