Used in research settings to quantify levels of human apolipoprotein B100 in biological samples such as serum or plasma. Apo-B100 is a key structural component of atherogenic lipoproteins including LDL and VLDL, making its measurement important in studies related to cardiovascular disease risk assessment. The ELISA kit enables high-throughput, specific, and sensitive detection of apo-B100, supporting investigations in lipid metabolism, atherosclerosis, and therapeutic interventions targeting cholesterol levels. Commonly used in clinical research laboratories and pharmaceutical development for biomarker validation.
