Used in biomedical research to quantify levels of acetyl-Coenzyme A acetyltransferase (ACAT) in rat tissue samples, particularly in studies related to lipid metabolism, mitochondrial function, and neurodegenerative diseases. The kit enables researchers to assess ACAT activity indirectly by measuring protein concentration in samples from brain, liver, or other organs, supporting investigations into metabolic disorders, Alzheimer's disease models, and energy metabolism pathways. It is designed for high-throughput analysis in laboratory settings using ELISA methodology, offering sensitivity and specificity for rat-derived samples. Commonly applied in preclinical studies and pharmaceutical research.
