Used in biomedical research to quantify mouse type III collagen levels in tissue extracts, serum, or cell culture supernatants. Helps assess extracellular matrix remodeling in studies related to fibrosis, wound healing, and tissue regeneration. Commonly applied in research on liver, lung, and cardiac fibrosis to monitor disease progression and evaluate therapeutic interventions. Provides a sensitive and specific means to measure collagen III, a key marker of early fibrotic changes and connective tissue turnover in mouse models.
