Used in biomedical research to quantify apolipoprotein E levels in mouse samples, aiding studies on lipid metabolism, atherosclerosis, and neurodegenerative diseases such as Alzheimer's. Enables researchers to assess Apo-E expression in plasma, serum, or tissue homogenates with high specificity and sensitivity. Commonly applied in preclinical studies involving transgenic mouse models to evaluate therapeutic interventions targeting cholesterol regulation or central nervous system repair mechanisms.
