Used in biomedical research to quantitatively measure human fibroblast growth factor 4 (FGF-4) levels in biological samples such as serum, plasma, and cell culture supernatants. This ELISA kit is particularly useful in studies related to cell proliferation, tissue repair, embryonic development, and angiogenesis. It supports research in cancer biology, as FGF-4 is involved in tumor growth and progression. The assay enables high sensitivity and specificity, allowing researchers to detect low concentrations of FGF-4, making it a valuable tool in both basic science and translational research settings.
