Abstract
A specific, precise and sensitive double-antibody radioimmunoassay for Neuropeptide Y (NPY) has been developed. There was no appreciable cross-reactivity with the structurally related peptides, peptide YY (PYY) and pancreatic polypeptide (PP). The minimum detectable plasma NPY level was 3 nM. Application of radioimmunoassay to canine models revealed that portal and systemic NPY levels increased significantly following a standard meal.
