Used in biomedical research to quantify Monkey Collagenase Fourth Subtype (CIV) levels in biological samples such as serum, plasma, and tissue homogenates. This ELISA kit enables researchers to study extracellular matrix degradation, particularly in models of fibrosis, liver disease, and inflammatory conditions where collagen breakdown is a key process. It supports high sensitivity and specificity, allowing accurate measurement of CIV concentrations to monitor disease progression or evaluate therapeutic interventions in non-human primate studies.
