Fatty acid-binding protein 1 (FABP1) also known as liver-type fatty acid-binding protein (L-FABP) is a protein that in humans is encoded by the FABP1 gene.FABP1 encodes the fatty acid-binding protein found in liver. Fatty acid binding proteins are a family of small, highly conserved, cytoplasmic proteins that bind long-chain fatty acids and other hydrophobic ligands. FABP1 and FABP6 (the ileal fatty acid binding protein) are also able to bind bile acids. It is thought that FABPs roles include fatty acid uptake, transport, and metabolism.

The antibody is stable for at least 1 year from the date of receipt when stored at -20°C to -70°C. Reconstituted antibody can also be aliquotted and stored at 4°C for 1 month or at -20°C to -70°C in a manual defrost freezer for many months without detectable loss activity. Please avoid freeze-thaw cycles.

This antibody binds to its immunogen, and did not show any cross reactivity with unrelated antigens in ELISA. Cross reactivity with mouse and rat FABP1 has not been tested yet.
