Used in biomedical research to quantify levels of TIMP-4 (tissue inhibitor of metalloproteinases-4) in human biological samples such as serum, plasma, and cell culture supernatants. It plays a key role in studying extracellular matrix remodeling processes linked to cardiovascular diseases, cancer progression, and inflammatory conditions. The kit enables accurate measurement of TIMP-4 concentration, helping researchers assess its role as a regulatory protein in matrix metalloproteinase (MMP) activity. Widely applied in clinical labs and pharmaceutical studies to investigate disease mechanisms and evaluate potential therapeutic targets.
