Used in biomedical research to quantify levels of TIMP-3 in biological samples such as tissue extracts, cell culture supernatants, and body fluids. Enables investigation of extracellular matrix remodeling processes involved in diseases like arthritis, cardiovascular disorders, and cancer. Supports studies on metalloproteinase regulation, inflammation, and tissue fibrosis. Commonly applied in preclinical research and drug development to assess biomarker expression and evaluate therapeutic efficacy.
