Used in biomedical research to quantify human type I collagen levels in biological samples such as cell culture supernatants, tissue extracts, and serum. This ELISA kit is particularly valuable in studies related to extracellular matrix formation, wound healing, fibrosis, and bone or connective tissue disorders. It enables researchers to assess collagen metabolism in diseases like osteoporosis, scleroderma, and liver fibrosis, as well as in tissue engineering and regenerative medicine applications where collagen production is a marker of cell differentiation and matrix deposition. The assay provides high specificity and sensitivity, allowing for accurate measurement even in complex sample matrices.
