Anti-Fatty acid-binding protein, heart Antibody

This rabbit polyclonal primary antibody from Antibodies.com targets Fatty acid-binding protein, heart (H-FABP / FABP3), a 15 kDa intracellular lipid-binding protein abundantly expressed in cardiomyocytes. The unconjugated reagent is supplied at 100 µg per vial and is validated for Western blot and immunohistochemistry on human samples, supporting research into cardiac energy metabolism, ischemic injury, and early myocardial infarction biomarker workup.

H-FABP shuttles long-chain fatty acids toward mitochondrial β-oxidation, and altered cytosolic levels have been reported in acute coronary syndrome, heart failure, and reperfusion-injury studies. Researchers apply this polyclonal reagent to probe cardiomyocyte-specific expression in fixed tissue sections by IHC and to detect the 15 kDa target band in cardiac lysates by WB. The polyclonal format recognizes multiple epitopes on the human target, giving broader tolerance for minor sample variation between patient-derived preparations.

For handling, store at -20 °C in working aliquots to limit freeze-thaw cycles and protect from light; the antibody is provided as 100 µg of unconjugated reagent, intended for research use only, and is reactive with human tissue.
