Used in biomedical research to quantify vascular endothelial growth factor B (VEGF-B) levels in biological samples such as serum, plasma, and cell culture supernatants. This ELISA kit enables researchers to study the role of VEGF-B in angiogenesis, endothelial cell survival, and vascular function. It is particularly useful in investigating cardiovascular diseases, metabolic disorders, and neurodegenerative conditions where VEGF-B signaling is involved. The assay provides high sensitivity and specificity, allowing accurate measurement of VEGF-B concentrations for both basic research and preclinical studies.
