Used to measure ACAT (Acyl-CoA:cholesterol acyltransferase) enzyme activity in rat samples, this ELISA kit is essential in research related to cholesterol metabolism. It enables quantification of ACAT activity in tissues or cells, supporting studies on atherosclerosis, fatty liver disease, and metabolic disorders. Commonly used in pharmaceutical research to evaluate drug effects on cholesterol esterification, it provides a reliable tool for assessing potential treatments targeting lipid-related diseases. The assay is also applied in diabetes and obesity research where altered cholesterol homeostasis plays a role.
