Used in biomedical research to quantify mouse apolipoprotein B levels in serum or plasma samples. Enables assessment of lipid metabolism in mouse models, particularly in studies related to atherosclerosis, cardiovascular disease, and metabolic disorders such as obesity and diabetes. Widely applied in preclinical studies to evaluate the impact of drugs, diets, or genetic modifications on lipoprotein profiles. Provides a reliable, sensitive, and high-throughput method for measuring apo-B concentration, supporting research in lipid biology and therapeutic development.
