Used in biomedical research to quantify human type III collagen levels in biological samples such as serum, plasma, and tissue homogenates. This kit is particularly valuable in studies related to fibrosis, wound healing, and connective tissue disorders. It enables researchers to assess collagen turnover in conditions like liver cirrhosis, pulmonary fibrosis, and scleroderma. Also applied in dermatological research to monitor skin aging and regeneration processes. The assay supports high sensitivity and specificity, making it suitable for detecting subtle changes in collagen III concentrations during disease progression or therapeutic intervention.
