Anti-NPY Antibody

The Anti-NPY polyclonal reagent from Antibodies.com is a rabbit-host primary antibody raised against the 36-amino acid neuropeptide Y, a regulator of feeding behavior, energy homeostasis, vasoconstriction, and stress signaling in mammals. Supplied as 100 µl of unconjugated antiserum suitable for Western blot and immunohistochemistry workflows on human, mouse, and rat samples.

Affinity-purified rabbit polyclonal antibodies targeting conserved regions of neuropeptide Y enable detection of endogenous NPY in hypothalamic tissue sections and neuronal lysates. The unconjugated format supports flexible reporter labeling in immunostaining and chemiluminescent immunoblotting protocols, allowing labs to choose HRP, fluorophore, or biotin secondaries matched to their existing assay setup. Reactivity characterization confirms recognition of the human, mouse, and rat orthologs, supporting translational neuroscience research into appetite circuits, anxiety, and sympathetic cardiovascular control.

Recommended starting dilution ranges are typical of polyclonal anti-peptide reagents and may require titration against reference lysates. Store refrigerated at 2 to 8 degrees C and protect from light to preserve binding activity over the working shelf life.
