Product Usage Information

Storage: Supplied in 10 mM sodium HEPES (pH 7.5), 150 mM NaCl, 100 µg/ml BSA and 50% glycerol. Store at –20°C. Do not aliquot the antibody.

Specificity / Sensitivity

FABP7 Antibody recognizes endogenous levels of total FABP7 protein.

Species predicted to react based on 100% sequence homology: Monkey

Source / Purification

Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues near the amino terminus of human FABP7 protein. Antibodies are purified by protein A and peptide affinity chromatography.

Fatty acid binding proteins (FABPs) bind to fatty acids and other lipids to function as cytoplasmic lipid chaperones (1). They participate in the transport of fatty acids and other lipids to various cellular pathways (2). Differential expression of FABPs is found in several types of tumors and their normal-cell counterparts (3). FABP7 is abundantly expressed in fetal brain and may be essential for development (4). Expression is required for the establishment of the radial glial fiber system, a system that is necessary for the development of cortical layers (5). Increased expression of FABP7 is associated with reduced survival in patients with glioblastoma (6), and is also found in glial cells following nerve injury (7). Investigators have found loss of FABP7 may be involved in the development and progression of breast cancer and expression of FABP7 has been shown to induce mammary differentiation and to inhibit growth of breast cancer cells (8,9).
