Used in research and clinical settings to study matrix metalloproteinase-9 (MMP-9) activity, this antibody helps in understanding inflammatory processes and tissue remodeling. It is applied in assays to detect, quantify, and inhibit MMP-9, an enzyme implicated in diseases such as cancer, ulcerative colitis, and arthritis. By selectively targeting MMP-9, it supports the development of therapies aimed at reducing extracellular matrix degradation and inflammation. It also serves as a reference standard in immunoassays and flow cytometry to evaluate the performance of other anti-MMP-9 agents.
