Anti-FABP4 Antibody

Fatty acid-binding protein 4 (FABP4) is a ~15 kDa intracellular lipid chaperone targeted by this rabbit polyclonal reagent from Antibodies.com. Supplied as an unconjugated IgG preparation at 1 mg/ml in PBS with 0.1% sodium azide and 50% glycerol, the antibody is validated for western blot, immunohistochemistry, and immunofluorescence workflows across human, mouse, and rat samples.

The 100 µl vial provides enough material for routine blotting and staining experiments in studies of adipogenesis, metabolic syndrome, atherosclerosis, and inflammatory disease. For storage, keep the glycerol-containing solution refrigerated to preserve antibody activity and limit freeze-thaw cycling. Researchers commonly apply this reagent to track adipocyte differentiation in 3T3-L1 cells, assess macrophage lipid-loading in atheroma plaques, and probe FABP4 expression in tumor microenvironments where it has been linked to cancer progression.

The polyclonal format offers broader epitope recognition than monoclonal alternatives, an advantage when detecting FABP4 across species or under varying fixation conditions during IHC.
