Fig. 9. Identified suboesophageal ganglion (SOG) neurones showing anti-cGMP immunoreactivity. (A) Mandibular closer motoneurone injected with Lucifer Yellow and photographed with an appropriate filter set. (B) The same neurone shows anti-cGMP immunostaining (CY3-labelled secondary antibody photographed with an appropriate filter set). (C) Salivary neurone 1 (SN1) labelled by backfilling of nerve 7B with dextran-amine-conjugated Lucifer Yellow. (D) SN1 is anti-cGMP-immunoreactive. (E) Salivary neurone 2 (SN2) labelled by backfilling of nerve 7B with dextran-amine-conjugated Lucifer Yellow. (F) SN2 does not show anti-cGMP immunoreactivity. Scale bars, 100 µm.
