Used in biomedical research to measure levels of apolipoprotein A1 in monkey serum or plasma samples. Helps in studying high-density lipoprotein (HDL) metabolism and cardiovascular health in non-human primate models. Commonly applied in preclinical studies related to atherosclerosis, lipid disorders, and evaluation of therapeutic interventions targeting cholesterol transport. Provides a reliable and specific method for quantifying Apo A1, supporting research in metabolic disease and drug development.
