Used in biomedical research to measure endothelial nitric oxide synthase (eNOS) levels in rabbit samples, this ELISA kit enables accurate quantification of eNOS protein in cell lysates, tissue homogenates, and biological fluids. It is widely applied in cardiovascular studies to investigate endothelial function, vascular health, and nitric oxide production. Researchers use it to assess the impact of drugs, oxidative stress, or disease conditions such as hypertension, atherosclerosis, and ischemia-reperfusion injury on eNOS expression. The assay supports high sensitivity and specificity, making it ideal for monitoring changes in eNOS during experimental treatments and for validating molecular pathways involved in vascular regulation.
