Eel brain contains a factor which exhibited a complete cross-reaction in a radioimmunoassay (RIA) for mammalian luteinizing hormone-releasing hormone (LHRH) and which exhibited a behavior similar to that of synthetic mammalian LHRH on Sephadex G-25.

Experiments are described that very strongly suggest that mammalian gonadotropins are the heterothyrotropic factors able to stimulate the 131I thyroidal uptake in teleost fish. Mammalian gonadotropins, like mammalian and teleostean thyrotropins appea
