Fig. 5. Anti-Khc injections blocked premature fast streaming in capu and spir mutants. Each panel is a projection of eight images from one focal plane acquired at 20-second intervals (see Movies 9-11 in the supplementary material). (A,B) Stage 11 wild-type oocytes injected with control antibody (A) or anti-Khc (B) show that antibody inhibition of kinesin-1 stopped normal fast streaming (see also Movies 9 and 10 in the supplementary material). (C,D) A capu¹/capu^HK oocyte before (C) and after (D) anti-Khc injection. (E,F) A spir¹/spir¹ oocyte before (E) and after (F) anti-Khc injection (Movie 11 in the supplementary material). Scale bars: in B, 50 µm for A,B; in D, 50 µm for C-F.
