Used in research settings to measure levels of procollagen type III N-terminal propeptide, a biomarker associated with collagen synthesis and tissue remodeling. Commonly applied in studies of liver fibrosis, where elevated levels indicate active fibrogenesis, allowing researchers to assess disease progression and response to treatment. Also utilized in dermatological research to evaluate skin repair and aging, as well as in cardiovascular studies linked to myocardial remodeling. The kit enables quantitative detection in biological samples such as serum or plasma, supporting non-invasive monitoring of connective tissue turnover in experimental models.
