The fatty-acid-binding proteins (FABPs) are a family of carrier proteins for fatty acids and other lipophilic substances such as eicosanoids and retinoids. These proteins are thought to facilitate the transfer of fatty acids between extra- and intracellular membranes. The fatty acid binding protein 4 (FABP4) and fatty acid binding protein 5 (FABP5) are closely related and both are expressed in adipocytes. Mice with targeted disruption of FABP4 accompany FABP5 almost completely to protect against diet-induced obesity, insulin resistance, dyslipidemia, type 2 diabetes, and fatty liver disease, while mice overexpressing FABP5 in adipose tissues have reduced insulin sensitivity.

Recombinant full-length human FABP5 expressed in E.coli.

The antibody detects human FABP5.

Liquid in phosphate-buffered saline (PBS).

Store at –20°C for less than one week. For long-term storage, aliquot and freeze at -70°C. Avoid repeated freeze/defrost cycles.

Western blot - This antibody can be used at 0.5-2 μg/mL with the appropriate secondary reagents to detect human FABP5.

Rabbit crude IgG was purified by protein-G column.
