Detects human FABP4/A‑FABP in direct ELISAs and human and mouse FABP4/A-FABP in Western blots. In direct ELISAs, 100% cross-reactivity with recombinant mouse (rm) FABP4, 50% cross-reactivity with recombinant human (rh) FABP3, 15% cross-reactivity with rhFABP3, and no cross-reactivity with rhFABP8 or rhFABP9 is observed.

Detection of Human and Mouse FABP4/A‑FABP by Western Blot. Western blot shows lysates of human adipose tissue and mouse adipose tissue. PVDF membrane was probed with 1 µg/mL of Rat Anti-Human FABP4/A‑FABP Monoclonal Antibody (Catalog # MAB3150) followed by HRP-conjugated Anti-Rat IgG Secondary Antibody (Catalog # HAF005). A specific band was detected for FABP4/A‑FABP at approximately 14 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

FABP4, also known as adipocyte P2 and A-FABP (adipocyte FABP), is a FABP family member that is expressed in adipocytes and monocyte-derived foam cells. It is a lipid transport protein that binds long chain fatty acid and retinoic acid. Human and mouse FABP4 share 91% amino acid sequence homology.
