Used to quantitatively measure total matrix metalloproteinase-7 levels in human biological samples such as serum, plasma, or tissue homogenates. Plays a key role in research related to tissue remodeling, arthritis, cancer progression, and inflammatory diseases by detecting both active and latent forms of MMP-3. Enables researchers to assess disease activity, monitor therapeutic response, and investigate the role of MMP-3 in pathophysiological processes. Widely applied in clinical labs and biomedical research for its high sensitivity and specificity.
