Fig. 2. Expression of DPTP52F protein. Whole-mount embryos were stained with mAb 13B8 using HRP immunohistochemistry. (A) A ventral view of a gastrulating embryo, showing DPTP52F at the edges of the ventral furrow (arrow). At this stage, DPTP52F is on the membranes of all cells in the embryo at lower levels. (B) A side view (anterior towards the left) of a stage 15 embryo. The ventral nerve cord (arrow) expresses DPTP52F. (C) Two segments of a dissected CNS from a stage 15 wild-type embryo. DPTP52F is expressed on cell bodies; axon tracts (arrow) are lighter. (D) A dissected CNS from a stage 15 Ptp52F18.3 embryo. No staining is observed.
