Used in biomedical research to detect and quantify matrix metalloproteinase 4 (MMP-4) in rat samples, this ELISA kit is essential for studying extracellular matrix remodeling. It is widely applied in inflammation, cardiovascular disease, and cancer research due to MMP-4's role in tissue degradation and repair. Researchers use it to measure protein levels in serum, plasma, and tissue homogenates, enabling insights into disease progression and therapeutic responses in rodent models. The assay provides high sensitivity and specificity, making it suitable for preclinical studies investigating metalloproteinase activity and inhibitor effects.
