Figure 2. Presynaptic localization of ITSN-1. (A-D) Worms (wild type [A-C];
itsn-1(
ok268) [D]) were stained with anti-ITSN-1 Ab (red). Worms are in lateral view, head to the left. NR, nerve ring (blue line in D); VC, ventral cord; DC, dorsal cord. (E and F) Epifluorescence of transgenic worms carrying the pitsn-1:ITSN1::GFP array. Worms are in ventral (E) and lateral views (F), head to the left. SC, sublateral cords; C, commissures. (G and H) Immunolocalization of ITSN-1 in the nIs52 strain (G; carrying the
punc-25:SNB-1::GFP array) or in the oxIs22 strain (H; carrying the
punc-49:UNC-49::GFP array). Red, ITSN-1; green, GFP epifluorescence. Dorsal cord is shown. Worms are in lateral view, head to the left. Bar, 10 um (all panels).
