Target description

Fatty acid-binding protein, adipocyte (UniProt: P15090; also known as Adipocyte lipid-binding protein, ALBP, Adipocyte-type fatty acid-binding protein, A-FABP, AFABP, Fatty acid-binding protein 4) is encoded by the FABP4 gene (Gene ID: 2167) in human. FABPs are a family of proteins that function as intracellular lipid chaperones and regulate lipid trafficking and responses in cells. They can reversibly bind to hydrophobic ligands, such as saturated and unsaturated long-chain fatty acids (FAs), eicosanoids, and other lipids, with high affinity and broad selectivity. FABP4 binds both long chain fatty acids and retinoic acid and delivers them to their cognate receptors in the nucleus. Its fatty acid binding sequence is localized to amino acids 127-129 and its nuclear localization signal resides in amino acids 27-32. FABP4 is mainly expressed in adipocytes, however, smaller amounts may also be found in macrophages. In adipocytes its levels are found to be about 10,000-fold higher than in macrophages. It is released from adipocytes in a non-classical pathway associated with lipolysis, possibly acting as an adipokine. Elevated levels of FABP4 have been linked to development of obesity, insulin resistance, diabetes mellitus, hypertension, and atherosclerosis. FABP4-deficient mice display increased body weight but reduced insulin resistance in both high-fat diet-induced and genetic obesity mouse models. Expression of FABP4 is reported to be high during adipocyte differentiation and is transcriptionally controlled by peroxisome proliferator-activated receptor (PPAR) agonists. This ZooMAbZooMAb^® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

Physical form

Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS with 5% Trehalose, normal appearance a coarse or translucent resin. The PBS/trehalose components in the ZooMAb formulation can have the appearance of a semi-solid (bead like gel) after lyophilization. This is a normal phenomenon. Please follow the recommended reconstitution procedure in the data sheet to dissolve the semi-solid, bead-like, gel-appearing material. The resulting antibody solution is completely stable and functional as proven by full functional testing. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 μL.

Reconstitution

300 μg/mL after reconstitution at 25 μL per vial. Please refer to guidance on suggested starting dilutions and/or titers per application and sample type.

Storage and Stability

Recommend storage of lyophilized product at 2-8°C; Before reconstitution, micro-centrifuge vials briefly to spin down material to bottom of the vial; Reconstitute each vial by adding 25 μL of filtered lab grade water or PBS; Reconstituted antibodies can be stored at 2-8°C, or -20°C for long term storage. Avoid repeated freeze-thaws.
