Used in biomedical research to measure levels of heme oxygenase-1 (HO-1) in rat tissue samples or biological fluids. HO-1 is an enzyme involved in oxidative stress response, inflammation, and cellular protection, making this kit valuable for studying conditions like liver injury, neurodegenerative diseases, lung disorders, and ischemia-reperfusion damage in rat models. The ELISA format allows for sensitive and specific quantification of HO-1 protein, supporting both academic research and drug development efforts focused on antioxidant pathways and inflammatory regulation.
