FABP4 (Adipocyte lipid-binding protein)

Fatty acid binding proteins (FABPs) are small cytoplasmic proteins that are expressed in a highly tissue-specific manner and bind to fatty acids such as oleic and retinoic acid. Adipocyte fatty-acid-binding protein, aP2 (FABP4) is expressed in adipocytes and macrophages, and integrates inflammatory and metabolic responses. Studies in aP2-deficient mice have shown that this lipid chaperone has a significant role in several aspects of metabolic syndrome, including type 2 diabetes and atherosclerosis. It regulates allergic airway inflammation and may provide a link between fatty acid metabolism and asthma.\n\nUniProt Number:\nP15090\n\nGene ID:\nFABP4\n\nApplications:\nSuitable for use in Western Blot.\n\nRecommended Dilution:\nOptimal dilutions to be determined by the researcher.\n\nStorage and Handling:\nStore at -20?C for one year.
