Used in biomedical research to quantify mouse apolipoprotein E4 (apo-E4) levels in biological samples such as plasma, serum, or tissue homogenates. This ELISA kit enables researchers to study the role of apo-E4 in lipid metabolism, neurobiology, and inflammatory processes, particularly in mouse models of Alzheimer's disease and atherosclerosis. It supports high-throughput analysis with high sensitivity and specificity, making it valuable for preclinical studies investigating disease mechanisms and therapeutic interventions targeting apolipoprotein-related pathways.
