Used in biomedical research to quantify apolipoprotein B100 levels in mouse serum or plasma samples. Helps in studying lipid metabolism, atherosclerosis development, and cardiovascular disease mechanisms in mouse models. Enables researchers to assess the impact of drugs, diets, or genetic modifications on apo-B100 expression and lipoprotein profiles. Widely applied in preclinical studies related to metabolic disorders and dyslipidemia.
