Nesfatin-1, derived from the protein NEFA/nucleobindin2 (NUCB2), is a newly identified peptide that acts as a potent satiety agent. It is an 82 amino acid peptide that suppresses food intake after intracerebroventricular injection. Nesfatin-1 and its precursor NUCB2 were identified by subtraction cloning in cell lines of both neuronal and adipocytic origin. It has been reported that peptides involved in the regulation of ingestive behavior are also involved in the regulation of the stress response. It is located in the hypothalamic nuclei, including the paraventricular nucleus (PVN) and supraoptic nucleus (SON). The conversion of NUCB2 into Nesfatin-1 is indispensable for its activity in vivo. Nesfatin-1 is found in discrete nuclei of the hypothalamus where it probably activates a leptin-independent melanocortin pathway. Nesfatin-1 crosses the Blood Brain Barrier (BBB) in both the blood-to-brain and brain-to-blood directions by a nonsaturable system. NUCB2 is also expressed in the adipocyte cell line 3T3L1 suggesting other functions of Nesfatin-1 outside brain or peripheral source of Nesfatin-1 affecting brain function.

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.

The rabbit anti-human Nesfatin antibody detects specifically target derived from human recombinant protein as well as KLH-conjugated synthetic peptide as immunogen. Cross reactivity with mouse and rat are expected from sequence similarity.
