Used in biomedical research to detect and quantify matrix metalloproteinase-13 (MMP-13) in rat samples, this ELISA kit is essential for studying tissue remodeling, cartilage degradation, and inflammatory processes. It is widely applied in osteoarthritis research, where MMP-13 plays a key role in breaking down type II collagen in joint cartilage. Researchers also use it to evaluate the effectiveness of therapeutic compounds targeting enzyme activity in preclinical models. The kit enables high sensitivity and specificity, making it suitable for analyzing biological fluids such as serum, plasma, synovial fluid, and cell culture supernatants. Its application supports drug development and mechanistic studies in inflammation, cancer metastasis, and connective tissue diseases.
