Used in biomedical research to measure levels of apolipoproteins in rat samples, this ELISA kit enables the study of lipid metabolism and cardiovascular diseases in preclinical models. It is commonly applied in studies related to atherosclerosis, metabolic syndrome, and diabetes where lipid transport and regulation are investigated. The kit supports quantitative analysis of protein expression changes in response to drug treatments or genetic modifications. It is also used in toxicology studies to assess impacts on liver function and lipid homeostasis.
