Characterisation of neurotensin-immunoreactivity in porcine ileum using region-specific radioimmunoassays and chromatographic fractionation: isolation and primary structure of porcine neurotensin.
1. Neurotensin-immunoreactivity has been characterised in porcine ileum using region-specific radioimmunoassay coupled to chromatographic fractionation. 2. Two immunoreactive peptides were identified. 3. Peptide 1 was immunochemically, chromatographically and structurally identical to bovine neurotensin. 4. Peptide 2 exhibited novel immunochemical and chromatographic characteristics and represents a new neurotensin-related peptide.
