Used in biomedical research to measure endothelial nitric oxide synthase (eNOS) levels in mouse tissue samples, particularly in studies related to vascular function and cardiovascular diseases. Helps researchers assess eNOS expression and activity in conditions such as hypertension, atherosclerosis, and ischemia-reperfusion injury. Commonly applied in preclinical studies using mouse models to investigate endothelial dysfunction and the effects of therapeutic compounds on nitric oxide production. Suitable for quantifying eNOS in cell lysates, plasma, and tissue homogenates, supporting drug development and mechanistic studies in vascular biology.
