Used in biomedical research to quantitatively measure decorin (DCN), a small leucine-rich proteoglycan, in tissue extracts, cell culture supernatants, or biological fluids. This ELISA kit enables researchers to study decorin’s role in extracellular matrix organization, collagen fibrillogenesis, and regulation of growth factors such as TGF-β. It is widely applied in studies related to fibrosis, wound healing, osteoarthritis, and cancer progression, where altered decorin expression impacts disease development. The assay provides high sensitivity and specificity, making it suitable for monitoring disease biomarkers and evaluating therapeutic responses in experimental models.
