Mad2 and Mps1 are not recruited to unattached kinetochores in 2-cell P. mammillata embryos. (a) Representative images of live eggs (top, middle rows) and 2-cell embryos (bottom row) expressing histone H2B-Venus and Mad2-Tomato. (b) Ratio of Mad2-Tomato fluorescence intensity in chromosome region (A) and cytoplasm (B) in nocodazole-treated eggs and 2-cell embryos (c) Representative images of live eggs (top) and 2-cell embryos (bottom) expressing histone H2-Venus and Mps1-Tomato. (d) Ratio of Mps1-Tomato fluorescence intensity in chromosome region (A) and cytoplasm (B) in nocodazole-treated eggs and 2-cell embryos. White squares in (a,c) indicate chromatin-containing regions enlarged (5×) on the right images. Scale bar = 30 µm.
