Using a radioimmunoassay for the sequence Arg-Phe-NH2 (RFamide), we have isolated the peptide less than Glu-Trp-Leu-Lys-Gly-Arg-Phe-NH2 (Pol-RFamide II) from acetic acid extracts of the hydromedusa Polyorchis penicillatus. This peptide is a neuropeptide and constitutes a peptide family together with less than Glu-Leu-Leu-Gly-Gly-Arg-Phe-NH2 (Pol-RFamide I), the first neuropeptide isolated from Polyorchis, and less than Glu-Gly-Arg-Phe-NH2 (Antho-RFamide), a neuropeptide isolated from sea anemones and sea pansies.
