Colocalization of Chb and Tubulin on the anterior MT network. Pictures represent midsagittal confocal planes of embryos oriented with their dorsal side up and anterior to the left. a-c anterior tip of nc 5 wild-type embryos stained for tyrosinated αTubulin using mab YL1,2 (a), Chb (b) and the merge of (a and b) in (c). d-f separate confocal section at the anterior tip of the same embryo as in (a-c) using a high magnification lens, stained for tyrosinated αTubulin using mab YL1,2 (d), Chb (e) and the merge of (d and e) in (f). Note the colocalization of freshly-made MT threads with Chb. Note the strong accumulation of Tubulin and Chb in the polar body (pb) in (a-c). Chb Chromosome bows. The whole confocal stack was also used to generate a 3D-Video (Additional file 3: Video S1)
