[Observation, by immunofluorescence, of an LH-RH-like antigen in the nervous system of Ciona inteesinalis (Tunicier ascidiacea)].

Using Rabbit anti-LH-RH antiserum for immunofluorescence, the presence of an LH-RH-like antigen was observed in the nervous system of a Protochordate Ciona intestinalis. Few immunoreactive cells are localized on the ventral posterior part between the nervous ganglion and the neural gland. Another group of cells are visible along the small nervous fibers near the dorsal vessel.
