Used in research settings to quantify levels of Collagenase I (also known as matrix metalloproteinase-1 or MMP-1) in biological samples such as cell culture supernatants, tissue extracts, and serum. This assay is particularly useful in studies related to extracellular matrix remodeling, wound healing, tissue regeneration, and fibrosis. It enables researchers to monitor enzymatic activity indirectly by measuring protein concentration, supporting investigations in dermatology, oncology, and inflammatory diseases. The kit provides a sensitive and specific method for high-throughput analysis in preclinical studies involving primate models or comparative biology where monkey-derived samples are analyzed.
