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.  NPY is widely expressed in the nervous system and has been shown to be differentially expressed in inhibitory interneurons in the hippocampus in degenerative disease, as a powerful vasoconstrictor in the periphery, and increased expression of NPY in the hypothalamus correlates with food intake.

In the rat central nervous system, immunohistochemistry has found NPY-like cell bodies in the cortex, caudate-putamen, hypothalamus (arcuate nucleus), hippocampus, anterior westolfactory 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.

Westerns are not recommended for the Neuropeptide Y antibody since the protein is too small to detect in gel.

Photo Description: IHC image of neurons staining for neuropeptide Y in the rat cortex (above) and striatum (below). The tissue was fixed with 4% formaldehyde in phosphate buffer, before being removed and prepared for vibratome sectioning. Floating sections were incubated at RT in 10% goat serum in PBS, before standard IHC procedure. Primary antibody was incubated at 1:5000 for 48 hours, goat anti-rabbit secondary was subsequently added for 1 hour after washing with PBS. Light microscopy staining was achieved with standard biotin-streptavidin/HRP procedure and DAB chromogen.

Love the results
We have used your NPY(Product ID: 22940) antibody and love the results we obtain with this antibody. While it is not as clear as your Vasopressin antibody (Product ID: 20069), it works very well for our research purposes. For NPY we use a dilution of 1:3000 and amplify with tyramide solution at a 1:50 dilution. It is mixed with 10% serum, 10% biotin diluted in 80% PBS-T and incubated for 48-72 hours at 4 degrees C. We used brain tissue from Thamnophis sirtalis (Red-sided garter snake).

Antibody Performed Very Well
Above IFC image entitled "C." is NPY interneurons (RED) in mouse striatum, GREEN staining is GFP expressed by medium spiny neurons. NPY antibody was used at 1:1000 dilution with the staining protocol described below. Antibody performed very well. Scale bar = 25 microns.

Immunohistochemistry: Mice were euthanized and perfused with PFA (4% in PBS), post fixed for 24 hrs, and their brains cryoprotected in 15% sucrose (24 hrs) followed by 30% sucrose (48 hrs). Coronal sections that included the corticostriatal, globus pallidus, or substantia nigra regions (30 um) were prepared using a microtome and then stored in PBS at 4C until processing. Sections were processed/stained in parallel as follows: Free floating sections were rinsed 3x with PBS and incubated 90 min at room temperature (RT) in PBS supplemented with donkey serum (5%) and Triton X-100 (1%). Primary antibody combinations were prepared as a master stock in PBS supplemented with donkey serum (2.5%) and Triton X-100 (0.5%) and applied to sections for 72 hrs at 4°C with gentle agitation. Sections were then rinsed 8x with PBS supplemented with Tween-20 (0.05%, at RT) and incubated with a secondary antibodies diluted in PBS supplemented with donkey serum (2.5%) and Triton X-100 (0.5%) for 1 hr at RT with gentle agitation, followed by 7 rinses with PBS and one rinse with deionized water. Sections were mounted onto slides and allowed to dry for ~18 hrs, after which cover slips were mounted with Vectashield and sealed with nail polish.
