Anti-FABP5 Antibody

Fatty acid-binding protein 5 (FABP5), also known as E-FABP or KFABP, is a small ~15 kDa cytoplasmic lipid chaperone that facilitates intracellular trafficking of long-chain fatty acids and their delivery to nuclear receptors such as PPARβ/δ. This unconjugated rabbit polyclonal reagent from Antibodies.com is raised against human FABP5 and ships as 100 µl of a 1 mg/ml stock formulated with 0.1% sodium azide and 50% glycerol as a cryoprotectant.

Validated applications cover Western blot, immunohistochemistry, and immunofluorescence, supporting studies of epidermal differentiation, lipid metabolism, and tumor biology. The antibody is widely cited in research on triple-negative breast cancer, squamous cell carcinoma, and cervical cancer, where elevated FABP5 levels correlate with proliferative signaling and prognosis. As a polyclonal reagent it tolerates minor sequence variation and provides flexibility across multiple sample types, including cultured cells, paraffin-embedded sections, and cryosections.

Store the vial refrigerated; for longer-term use, aliquot and freeze to minimize repeated freeze-thaw cycles, and protect from light. The product is intended for research use only and is not approved for diagnostic or therapeutic applications.
