Used in biomedical research to quantify human type II collagen levels in biological samples such as serum, synovial fluid, or tissue extracts. This ELISA kit is particularly valuable in studies related to cartilage degradation and joint diseases like osteoarthritis and rheumatoid arthritis. It enables researchers to monitor disease progression, evaluate the effectiveness of therapeutic agents targeting cartilage preservation, and investigate mechanisms of extracellular matrix remodeling. The assay is widely applied in clinical research and pharmaceutical development for its sensitivity and specificity in detecting ColⅡ biomarkers.
