Used to measure lysyl oxidase (LOX) enzyme activity in rat biological samples such as tissue homogenates, serum, or cell culture supernatants. This kit is commonly applied in research focused on extracellular matrix formation, collagen cross-linking, and tissue fibrosis. It helps in studying diseases like liver fibrosis, pulmonary fibrosis, and cancer metastasis where LOX activity plays a key role. The assay enables quantitative analysis through a colorimetric detection method, allowing researchers to assess changes in enzyme activity under experimental conditions. Widely used in preclinical studies and drug development to evaluate therapeutic targets related to connective tissue remodeling.
