Rat FABP3 (Fatty Acid Binding Protein 3, Muscle and Heart) ELISA Kit (RTES00725)

Heart-type fatty acid-binding protein (H-FABP), encoded by the FABP3 gene, is a 15 kDa cytoplasmic carrier expressed predominantly in cardiac myocytes and skeletal muscle fibers, where it shuttles long-chain fatty acids toward mitochondrial β-oxidation and ATP synthesis. The Assay Genie Rat FABP3 ELISA Kit provides researchers with a quantitative tool for measuring circulating FABP3 in rat-derived specimens, supporting investigations into myocardial injury, ischemic heart disease, lipid metabolism, and skeletal muscle pathophysiology.

This immunoassay enables quantification of FABP3 release kinetics in rodent models of cardiac ischemia-reperfusion, exercise-induced muscle damage, and metabolic disorders such as diabetes and obesity. Because H-FABP diffuses rapidly from injured cardiomyocytes into circulation, it serves as an early indicator of myocardial membrane disruption, complementing later-rising cardiac markers such as troponin. Researchers employ this kit in studies of fatty acid transport regulation, mitochondrial bioenergetics, and the role of FABP family members in insulin sensitivity and exercise physiology.

The kit ships as a 96-assay configuration with all reagents and protocol documentation needed to run the plate. Specimens should be aliquoted promptly and stored refrigerated when not in use to preserve analyte integrity. Intended for research use only.
