Used in biomedical research to quantitatively measure levels of lecithin cholesterol acyl transferase (LCAT) in rat biological samples such as serum or plasma. This assay is particularly valuable in studies related to lipid metabolism, atherosclerosis, and cardiovascular diseases. By enabling accurate detection of LCAT activity and concentration, the kit supports investigation into metabolic disorders, liver function, and the impact of therapeutic interventions in rodent models. It is commonly used in preclinical research and drug development where rat models are employed to understand cholesterol homeostasis and related pathologies.
