| pubmed-article:3951682 | pubmed:abstractText | Studies have revealed that the corpus luteum (CL) of the sheep releases oxytocin (OT) -like immunoreactivity under normal and physiological conditions. We have now purified and completely characterized the OT-like species from ovine CL and established by Edman degradation and comparative reverse-phase HPLC its identity with hypothalamic oxytocin. On the basis of radioimmunoassay, the characterized oxytocin was the only peptide possessing OT-like immunoreactivity. This study represents the first identification by sequence analysis of oxytocin outside the central nervous system. | lld:pubmed |
