Fig. 2. UNC-119 is expressed in neurons. (A) GFP was expressed in the GABA motorneuron cell bodies (arrows) and axons (**) in a wild-type worm expressing a Punc-47::GFP construct. (B) In the same wild-type individual, anti-UNC-119 antibodies labeled multiple cell bodies (arrowhead and arrows) and axons in the left (*) and right (**) ventral nerve cords. (C) GFP was also expressed in the GABA motorneuron commissures of wild-type worm carrying a Punc-47::GFP construct (right ventral nerve cord: **, axon: arrow). (D) Anti-UNC-119 antibodies labeled the axons in the right ventral nerve cord (**), the commissures seen in (C, arrow), and the lateral nerve cord (arrowhead). Scale bar (A-D) 5 µm.
