Used in biomedical research to quantify apolipoprotein B levels in sheep plasma or serum samples. Enables studies on lipid metabolism, cardiovascular health, and atherosclerosis in ovine models. Widely applied in veterinary research, animal nutrition studies, and metabolic disease modeling. Supports development and validation of therapeutic interventions targeting cholesterol regulation. Provides high sensitivity and specificity for accurate detection of apo-B concentrations in experimental settings.
