Used to quantitatively measure total matrix metalloproteinase-1 (MMP-1) in human biological samples such as serum, plasma, or tissue culture supernatants. It is widely applied in research related to extracellular matrix degradation, arthritis, cancer progression, and fibrotic diseases. The kit enables detection of both active and inactive forms of MMP-1, making it valuable for studying disease mechanisms involving tissue remodeling and inflammation. Commonly used in biomedical laboratories and clinical research settings to assess MMP-1 levels as a biomarker for disease activity or therapeutic response.
