Used in research to measure levels of type III procollagen amino-terminal peptide, a biomarker associated with collagen synthesis and tissue remodeling. Commonly applied in studies of liver fibrosis, where elevated levels indicate active fibrogenesis. Also utilized in dermatological research to assess skin wound healing and connective tissue disorders. The ELISA format allows for sensitive and specific quantification in biological samples such as serum or plasma, supporting both clinical research and drug development efforts targeting fibrotic diseases.
