Used in biomedical research to quantify apolipoprotein B48 levels in human serum or plasma samples. Helps assess intestinal lipoprotein production and chylomicron metabolism. Commonly applied in studies related to lipid disorders, insulin resistance, metabolic syndrome, and type 2 diabetes. Enables researchers to investigate postprandial lipemia and cardiovascular risk factors associated with remnant lipoproteins. Suitable for use in clinical labs and research settings where accurate measurement of apo-B48 is needed to understand dietary fat absorption and atherogenic particle levels.
