Neuropeptide Y Antibody (22940)

Neuropeptide Y (NPY) is a member of a regulatory peptide family and has a marked sequence homology with pancreatic polypeptide (PP) and peptide YY (PYY), which are other members of the family. In the rat central nervous system, immunohistochemistry has found NPY-like cell bodies in the cortex, caudate-putamen, hypothalamus (arcuate nucleus), hippocampus, anterior olfactory bulb, nucleus accumbens, amygdaloid complex and periaqueductal grey. NPY-like fibers and terminals are detected in high numbers in the bed nucleus of the stria terminalis, the peri- and paraventricular regions of the hypothalamus and thalamus and in discrete hypothalamic nuclei, particularly the suprachiasmatic nucleus. It has been used to detect NPY in a wide range of species including rat, mouse, human (1-7), fish, cat, bird, guinea pig, zebrafish, squirrels, frog, and newt.
