title: [Homologous radioimmunoassay of a hypothalamic factor stimulating salmon pituitary gonodatropic function (sGnRH)].
abstract: A radioimmunoassay for Salmon Gn-RH p-gly-His-Trp-Ser-Tyr-Gly-Trp- Leu-Pro-Gly) (NH2) has been developed with a sensitivity of 7 pg/assay tube. The system allows the specific detection of an immunological GnRH related substance in the brain and pituitary of three teleost species but not in an elasmobranch the Dogfish. these results are discussed and some Gn-RH contents of the organs are proposed.
