Used in biomedical research to quantify levels of platelet-derived growth factor D (PDGF-D) in biological samples such as serum, plasma, and cell culture supernatants. This ELISA kit is particularly valuable in studies related to tissue repair, angiogenesis, and fibrosis, where PDGF-D plays a regulatory role. It is also employed in cancer research, as elevated PDGF-D expression has been linked to tumor progression and metastasis in various malignancies. The assay enables high sensitivity and specificity, allowing researchers to monitor disease mechanisms and evaluate therapeutic interventions targeting PDGF signaling pathways.
