Neuromedin U-25 and its C-terminal octapeptide, neuromedin U-8 are related peptides originally identified in porcine brain which elicit potent uterus stimulant activity. Radioimmunoassay using an antiserum raised against porcine neuromedin U-8, indicated that neuromedin U-like immunoreactivity in the rat was far more abundant in the small intestine than the brain. Neuromedin U in the rat is a single, a 23 amino acid peptide (2, 17). Rat neuromedin U has the same 7 residues on its C-terminus as porcine neuromedin U, and the antiserum against porcine neuromedin U-8 is 100% crossreactive with rat neuromedin U. Immunohistochemical analyses using this antiserum revealed that neuromedin U-immunoreactive structures in rat intestine were confined to the enteric nervous system, implying that neuromedin U may be involved in neuronal regulation of gut function.

D011863 Radioimmunoassay Classic quantitative assay for detection of antigen-antibody reactions using a radioactively labeled substance (radioligand) either directly or indirectly to measure the binding of the unlabeled substance to a specific antibody or other receptor system. Non-immunogenic substances (e.g., haptens) can be measured if coupled to larger carrier proteins (e.g., bovine gamma-globulin or human serum albumin) capable of inducing antibody formation. Radioimmunoassays
