Used in research and development of cancer therapeutics due to its role in angiogenesis and tumor growth. Binds to VEGF165, inhibiting its interaction with receptors on endothelial cells, thus suppressing blood vessel formation in tumors. Employed in immunoassays and protein interaction studies to detect and quantify VEGF signaling components. Serves as a critical reagent in studying neuropilin-1 mediated pathways in immune regulation and neuronal development. Its Fc tag enables easy detection and purification, and supports use in antibody-based assays and potential biologics development.
