Figure 3. GPB-2 localization in wild-type animals. Wild-type animals were stained by indirect immunofluorescence using affinity-purified antibodies against GPB-2, and examined by confocal microscopy. (a) Image of the head region showing the localization of GPB-2 to the nerve ring (short arrow) and the ventral nerve cord that runs the length of the animal (long arrow). (b) Magnification of a single focal plane of the same animal shown in (a). Staining is observed at the membranes of the neuron cell bodies (the position of cell bodies is indicated by the bracket). The nerve ring is indicated by a short arrow. The ventral nerve cord is not in the focal plane shown. Anterior is left and dorsal is down in (a) and (b). (c) Image of the midbody, in which GPB-2 stains the membranes of body wall muscle cells (short arrow). The long arrow indicates the position of the ventral nerve cord. Anterior is left and ventral faces front in this image
