Anti-FABP5 Antibody

This polyclonal antibody from Antibodies.com targets human Fatty Acid-Binding Protein 5 (FABP5), a 15 kDa intracellular lipid chaperone implicated in fatty acid uptake, transport, and intracellular trafficking. Expressed across epidermal keratinocytes, adipocytes, macrophages, and select neuronal populations, FABP5 has been investigated as a biomarker in psoriasis and atopic dermatitis studies, and as a contributor to lipid-driven tumor progression in triple-negative breast carcinoma, prostate cancer, and bladder cancer xenograft models.

Raised in rabbit and supplied as an unconjugated 100 µl liquid aliquot, the reagent is validated for western blot and immunofluorescence workflows. Researchers frequently apply it to study PPARβ/δ signaling, cutaneous lipid metabolism, and the epithelial-mesenchymal transition in aggressive tumor subtypes. Human reactivity is confirmed, and the polyclonal format broadens epitope coverage for detecting endogenous protein levels in cell lysates and fixed tissue sections.
