Used in biomedical research to quantify levels of Neuropilin-1 (NRP-1) in human biological samples such as serum, plasma, and cell culture supernatants. This ELISA kit enables researchers to study NRP-1's role in angiogenesis, cancer progression, and neuronal development. It is widely applied in oncology and neuroscience fields to investigate tumor growth, metastasis, and vascular formation, as NRP-1 acts as a co-receptor for growth factors like VEGF and semaphorins. The assay provides high sensitivity and specificity, making it suitable for monitoring disease biomarkers and evaluating therapeutic responses in experimental models.
